title: "Supermarine Spitfire" content: Mitchell, chief designer at Supermarine Aviation Works, which operated as a subsidiary of Vickers-Armstrong from 1928. Mitchell pushed the Spitfire's distinctive elliptical wing designed by Beverley Shenstone to have the thinnest possible cross-section, helping give the aircraft a higher top speed than several contemporary fighters, including the Hawker Hurricane. Mitchell continued to refine the design until his death in 1937, whereupon his colleague Joseph Smith took over as chief designer, overseeing the Spitfire's development through . During the Battle of Britain, from July to October 1940, the public perceived the Spitfire to be the main RAF fighter, though the more

title: "Supermarine Spitfire" content: numerous Hurricane shouldered a greater proportion of the burden against Nazi Germany's air force, the Luftwaffe. However, Spitfire units had a lower attrition rate and a higher victory-to-loss ratio than those flying Hurricanes because of the Spitfire's higher performance. During the battle, Spitfires were generally tasked with engaging Luftwaffe fighters—mainly Messerschmitt Bf 109E-series aircraft, which were a close match for them. After the Battle of Britain, the Spitfire superseded the Hurricane to become the backbone of RAF Fighter Command, and saw action in the European, Mediterranean, Pacific, and South-East Asian theatres. Much loved by its pilots, the Spitfire served in

In February 1936, the director of Vickers-Armstrong, Sir Robert MacLean, guaranteed production of five aircraft a week, beginning 15 months after an order was placed. On 3 June 1936, the Air Ministry placed an order for 310 aircraft, at a cost of £1,395,000. Full-scale production of the Spitfire began at Supermarine's facility in Woolston, but order clearly could not be completed in the 15 months promised. Supermarine was a small company, already busy building Walrus and Stranraer flying boats, and Vickers was busy building Wellington bombers. The initial solution was to

title: "Supermarine Spitfire" content: the Rolls-Royce Merlin engine at £2,000, followed by the wings at £1,800 a pair, guns and undercarriage, both at £800 each, and the propeller at £350. In 1935, the Air Ministry approached Morris Motors Limited to ask how quickly their Cowley plant could be turned to aircraft production. In 1936, this informal request for major manufacturing facilities was turned into a formal scheme, known as the shadow factory plan, to boost British aircraft production capacity under the leadership of Herbert Austin. He was given the task of building nine new factories, and to supplement the existing British car manufacturing industry

As the largest Spitfire factory in the UK, by producing a maximum of 320 aircraft per month, it built 12,000 aircraft of this type, before its closure in 1945. During the Battle of Britain, the Luftwaffe made concerted efforts to destroy the main manufacturing plants at Woolston and Itchen, near Southampton. The first bombing raid, which missed the factories, came on 23 August 1940. Over the next month, other raids were mounted until, on 26 September

title: "Supermarine Spitfire" content: Great Britain. German bombers would have to fly to the UK over the North Sea, and Germany did not have any single-engine fighters with the range to accompany them. To carry out the mission of home defence, the design was intended to allow the Spitfire to climb quickly to intercept enemy bombers. The Spitfire's airframe was complex. The streamlined, semi-monocoque, duralumin-skinned fuselage featured a number of compound, vertical curves built up from a skeleton of 19 formers, also known as frames, starting from frame number one, immediately behind the propeller unit, to the tail unit attachment frame. The first four

title: "Supermarine Spitfire" content: at high speed would avoid unintended aileron reversal, throwing the aircraft around and potentially pulling the wings off. Air combat was also felt to take place at relatively low speeds and high-speed manoeuvring would be physically impossible. Flight tests showed the fabric covering of the ailerons "ballooned" at high speeds, adversely affecting the aerodynamics. Replacing the fabric covering with light alloy dramatically improved the ailerons at high speed. During the Battle of Britain, pilots found the Spitfire's ailerons were far too heavy at high speeds, severely restricting lateral manoeuvres such as rolls and high-speed turns, which were still a feature

title: "Supermarine Spitfire" content: structure with a light alloy skin attached using brass screws. The light alloy split flaps at the trailing edge of the wing were also pneumatically operated via a finger lever on the instrument panel. Only two positions were available; fully up or fully down (85°). Flaps were normally lowered only during the final approach and for landing, and the pilot was to retract them before taxiing. The ellipse also served as the design basis for the Spitfire's fin and tailplane assembly, once again exploiting the shape's favourable aerodynamic characteristics. Both the elevators and rudder were shaped so that their centre

This wing was tested on a modified F Mk 21, also called the F Mk 23, (sometimes referred to as "Valiant" rather than "Spitfire"). The increase in performance was minimal and this experiment was abandoned. Supermarine developed a new laminar-flow wing based on new aerofoil profiles developed by the National Advisory Committee for Aeronautics in the United States, with the objective of reducing drag and improving performance. These laminar-flow airfoils were the Supermarine 371-I used at the root and the 371-II used at the tip. Supermarine estimated that the

title: "Supermarine Spitfire" content: the arming of the Spitfire (and the Hurricane) is told in Captain C. H. Keith's book "I Hold my Aim". Keith held various appointments with the RAF dealing with designing, development and technical policy of armament equipment. He organised a conference, with Air Commodore Tedder in the chair, on 19 July 1934. He says "I think it can be reasonably contended that the deliberations of that conference made possible, if not certain, of the winning of the Battle of Britain, almost exactly six years later". At that meeting, scientific officer Captain F.W. 'Gunner' Hill presented charts based on his calculations

title: "Supermarine Spitfire" content: more reliable installation with an improved feed mechanism and four .303s in the outer wing panels. The modified fighters were then delivered to 19 Squadron. The operational history of the Spitfire with the RAF began with the first Mk Is "K9789", which entered service with 19 Squadron at RAF Duxford on 4 August 1938. The Spitfire achieved legendary status during the Battle of Britain, a reputation aided by the famous "Spitfire Fund" organised and run by Lord Beaverbrook, the Minister of Aircraft Production. In fact, the Hurricane outnumbered the Spitfire throughout the battle, and shouldered the burden of the defence

In the Mediterranean, the Spitfire blunted the heavy attacks on Malta by the Regia Aeronautica and Luftwaffe, and from early 1943, helped pave the way for the Allied invasions of Sicily and Italy. On 7 March 1942, 15 Mk Vs carrying 90-gallon fuel tanks under their bellies took off from off the coast of Algeria on a flight to Malta. Those Spitfire Vs were the first to see service outside Britain. The Spitfire also served on the Eastern Front; about a thousand were supplied

As the war progressed, the C wing became more common. Another armament variation was the E wing which housed two 20 mm (.79 in) cannon and two .50 in (12.7 mm) Browning machine guns. Although the Spitfire continued to improve in speed and armament because of its limited fuel capacity its range and endurance were limited: it remained "short-legged" throughout its life

Currently several of the trainers are known to exist, including both the T Mk VIII, a T Mk IX based in the US, and the "Grace Spitfire" "ML407", a veteran flown operationally by 485(NZ) Squadron in 1944. The Seafire, a name derived from "sea", and "Spitfire", was a naval version of the Spitfire specially adapted for operation from aircraft carriers. Although the Spitfire was not designed for the rough-and-tumble

title: "Supermarine Spitfire" content: too late to see service in World War II. The first Rolls-Royce Griffon-engined Mk XII flew in August 1942, and first flew operationally with 41 Squadron in April 1943. This mark could nudge in level flight and climb to an altitude of in under nine minutes. As American fighters took over the long-range escorting of United States Army Air Forces (USAAF) daylight bombing raids, the Griffon-engined Spitfires progressively took up the tactical air superiority role, and played a major role in intercepting V-1 flying bombs, while the Merlin-engined variants (mainly the Mk IX and the Packard-engined Mk XVI) were adapted

This was also the last known flight of a piston-engined fighter in the RAF. The last nation in the Middle East to operate Spitfires was Syria, which kept its F 22s until 1953. In late 1962, Air Marshal Sir John Nicholls instigated a trial when he flew Spitfire "PM631", a PR Mk 19 in the custody of the Battle of Britain Memorial Flight, against an English Electric Lightning F 3 (a supersonic jet-engined interceptor)

At the time British Commonwealth forces were involved in possible action against Indonesia over Malaya and Nicholls decided to develop tactics to fight the Indonesian Air Force P-51 Mustang, a fighter that had a similar performance to the PR Mk 19. The first airframe (PM631) developed mechanical issues which removed it from the trial. Another PR Mk 19, "PS853", which is now owned by Rolls-Royce, was on gate-guard duties at Binbrook, having been retired from the Battle of Britain Memorial Flight (BBMF) one year before. It had been maintained in running condition by ground

There are 54 Spitfires and a few Seafires in airworthy condition worldwide, although many air museums have examples on static display, for example, Chicago's Museum of Science and Industry has paired a static Spitfire with a static Ju 87 R-2/Trop. Stuka dive bomber. The oldest surviving Spitfire is a Mark 1, serial number "K9942"; it is preserved at the Royal Air Force Museum Cosford in Shropshire. This aircraft was the 155th built and first flew in April 1939. It

After repair, it was used for training until August 1944, when it became one of several Battle of Britain aircraft veterans that were allocated to the Air Historical Branch for future museum preservation. What may be the most originally restored Spitfire in the world is maintained at Fantasy of Flight in Polk City, Florida. Over a six-year period in the 1990s, this aircraft was slowly restored by Personal Plane Services in England using almost 90% of its original aircraft skins. Owner Kermit

Supermarine Aircraft – originally from Brisbane, Australia, and now based in Cisco, Texas – manufacture the 80% scale Spitfire Mk26 and the 90% scale Mk26B replicas. Their Supermarine Aircraft Spitfire is supplied in kit form and is the only all-aluminium reproduction Spitfire in production. The Isaacs Spitfire (1975) and the Time Warp Spitfire Mk V (1996) are homebuilt 60% scale replicas. During and after the Battle of Britain the Spitfire became a symbol of British resistance: for example, Lord Beaverbrook's "Spitfire Fund" of 1940 was one campaign which drew widespread public attention to the Spitfire.

The first six aircraft produced were designated Series 1, indicating that they were prototype aircraft. The initial production run consisted of Series 100 aircraft, serial numbers seven to 115 inclusive. In 1968, Series 200 production began with serial number 116. Changes made at the beginning of Series 200 production included improving the STOL performance, adding a longer nose that was equipped with a larger baggage compartment (except for aircraft fitted with floats), and fitting a larger door to the rear baggage compartment.

title: "Tupolev Tu-154" content: Tupolev Tu-154 The Tupolev Tu-154 (; NATO reporting name: "Careless") is a three-engine medium-range narrow-body airliner designed in the mid-1960s and manufactured by Tupolev. A workhorse of Soviet and (subsequently) Russian airlines for several decades, it carried half of all passengers flown by Aeroflot and its subsidiaries (137.5 million/year or 243.8 billion passenger km in 1990), remaining the standard domestic-route airliner of Russia and former Soviet states until the mid-2000s. It was exported to 17 non-Russian airlines and used as a head-of-state transport by the air forces of several countries. With a cruising speed of the Tu-154 is one of

title: "Tupolev Tu-154" content: the fastest civilian aircraft in use and has a range of . Capable of operating from unpaved and gravel airfields with only basic facilities, it was widely used in the extreme Arctic conditions of Russia's northern/eastern regions where other airliners were unable to operate. Originally designed for a 45,000 hour service life (18,000 cycles) but capable of 80,000 hours with upgrades, it was expected to continue in service until 2016, although noise regulations have restricted flights to western Europe and other regions. In January 2010 Russian flag carrier Aeroflot announced the retirement of its Tu-154 fleet after 40 years, with

title: "Tupolev Tu-154" content: the last scheduled flight being Aeroflot Flight 736 from Ekaterinburg to Moscow on 31 December 2009. Since 1968 there have been 39 fatal incidents involving the Tu-154, most of which were caused either by factors unrelated to the aircraft, incorrect maintenance, or by its extensive use in demanding conditions. The Tu-154 was developed to meet Aeroflot's requirement to replace the jet-powered Tu-104 and the Antonov An-10 and Ilyushin Il-18 turboprops. The requirements called for either a payload capacity of with a range of while cruising at , or a payload of with a range of while cruising at . A

title: "Tupolev Tu-154" content: takeoff distance of at maximum takeoff weight was also stipulated as a requirement. Conceptually similar to the British Hawker Siddeley Trident, which first flew in 1962, and the American Boeing 727, which first flew in 1963, the medium-range Tu-154 was marketed by Tupolev at the same time as Ilyushin was marketing the long-range Ilyushin Il-62. The Soviet Ministry of Aircraft Industry chose the Tu-154 as it incorporated the latest in Soviet aircraft design and best met Aeroflot's anticipated requirements for the 1970s and 1980s. The first project chief was Sergey Yeger; in 1964, Dmitryi S. Markov assumed that position. In

title: "Tupolev Tu-154" content: 1975, the project lead role was turned over to Aleksandr S. Shengardt. The Tu-154 first flew on 4 October 1968. The first deliveries to Aeroflot were in 1970 with freight (mail) services beginning in May 1971 and passenger services in February 1972. There was still limited production of the 154M model as of January 2009 despite previous announcements of the end of production in 2006. 1025 Tu-154s have been built, 214 of which were still in service as of 14 December 2009. The last serial Tu-154 was delivered to the Russian Defense Ministry on 19 February 2013 from the Aviakor

title: "Tupolev Tu-154" content: factory, equipped with upgraded avionics, a VIP interior and a communications suite. The factory has four unfinished hulls in its inventory which can be completed if new orders are received. The Tu-154 is powered by three rear-mounted low-bypass turbofan engines arranged similarly to those of the Boeing 727, but it is slightly larger than its American counterpart. Both the 727 and the Tu-154 use an S-duct for the middle (Number 2) engine. The original model was equipped with Kuznetsov NK-8-2 engines, which were replaced with Soloviev D-30KU-154 in the Tu-154M. All Tu-154 aircraft models have a relatively high thrust-to-weight-ratio which

title: "Tupolev Tu-154" content: give excellent performance, at the expense of lower fuel efficiency. This became an important factor in later decades as fuel costs grew. The flight deck is fitted with conventional dual yoke control columns. Flight control surfaces are hydraulically operated. The cabin of the Tu-154, although of the same six-abreast seating layout, gives the impression of an oval interior, with a lower ceiling than is common on Boeing and Airbus airliners. The passenger cabin accommodates 128 passengers in a two-class layout and 164 passengers in single-class layout, and up to 180 passengers in high-density layout. The layout can be modified to

title: "Tupolev Tu-154" content: what is called a winter version where some seats are taken out and a wardrobe is installed for passenger coats. The passenger doors are smaller than on its Boeing and Airbus counterparts. Luggage space in the overhead compartments is very limited. Like the Tupolev Tu-134, the Tu-154 has a wing swept back at 35° at the quarter-chord line. The British Hawker Siddeley Trident has the same sweepback angle, while the Boeing 727 has a slightly smaller sweepback angle of 32°. The wing also has anhedral (downward sweep) which is a distinguishing feature of Russian low-wing airliners designed during this era.

title: "Tupolev Tu-154" content: Most Western low-wing airliners such as the contemporary Boeing 727 have dihedral (upward sweep). The anhedral means that Russian airliners have poor lateral stability compared to their Western counterparts, but also have weaker Dutch roll tendencies. Considerably heavier than its predecessor Soviet-built airliner the Ilyushin Il-18, the Tu-154 was equipped with an oversized landing gear to reduce ground load, enabling it to operate from the same runways. The aircraft has two six-wheel main bogies fitted with large low-pressure tires that retract into pods extending from the trailing edges of the wings (a common Tupolev feature), plus a two-wheel nosegear unit.

title: "Tupolev Tu-154" content: Soft oleo struts (shock absorbers) provide a much smoother ride on bumpy airfields than most airliners, which very rarely operate on such poor surfaces. The original requirement was to have a three-person flight crew – captain, first officer and flight engineer – as opposed to a four- or five-person crew, as on other Soviet airliners. It became evident that a fourth crew member, a navigator, was still needed, and a seat was added on production aircraft, although their workstation was compromised due to the limitations of the original design. Navigators are no longer trained and this profession is becoming obsolete

title: "Tupolev Tu-154" content: with the retirement of the oldest Soviet-era planes. The latest variant (Tu-154M-100, introduced 1998) includes an NVU-B3 Doppler navigation system, a triple autopilot, which provides an automatic ILS approach according to ICAO category II weather minima, an autothrottle, a Doppler drift and speed measure system (DISS), and a "Kurs-MP" radio navigation suite. A stability and control augmentation system improves handling characteristics during manual flight. Modern upgrades normally include modernised TCAS, GPS, and other systems (mostly American-made or EU-made). Early versions of the Tu-154 cannot be modified to meet the current Stage III noise regulations and are no longer allowed to

title: "Tupolev Tu-154" content: fly into airspace where such regulations are enforced, such as the European Union. However, the Tu-154M's D-30 engines can be fitted with hush kits, allowing them to meet noise regulations. Many variants of this airliner have been built. Like its western counterpart, the 727, many of the Tu-154s in service have been hush-kitted, and some converted to freighters. As of August 2017, there are 44 Tupolev Tu-154 aircraft of all variants still in civil or military service. A 45th aircraft has been sighted flying with Air Kyrgyzstan in 2017, but is not listed by the airline as part of its

title: "Tupolev Tu-154" content: fleet. The remaining operators are: In February 2011, all remaining Iranian Tu-154s were grounded after two incidents. On 27 December 2016, the Russian Ministry of Defence announced that it had grounded all of its Tu-154s until the end of the investigation into the December 2016 crash of a 1983 Tupolev Tu-154. This was followed by the grounding of all Tu-154s in Russia. The Tu-154 had crashed into the Black Sea just after takeoff from Sochi, Russia, on 25 December 2016 killing all 92 people on board, including 64 members of the Alexandrov Ensemble, an official army choir of the Russian

title: "Tupolev Tu-154" content: Armed Forces. The Red Army Choir singers and dancers were en route to Syria to entertain Russian troops in the run-up to the New Year. Between 1970 and December 2016 there have been 110 serious incidents involving the Tu-154, and 69 hull losses, 30 of which did not involve fatalities. Of the fatal incidents, five resulted from terrorist or military terrorist action (two other wartime losses were non fatal), several from poor runway conditions in winter (including one in which the airplane struck snow plows on the runway), cargo overloading in the lapse of post-Soviet federal safety standards, and mid-air

Other incidents resulted from mechanical problems (two cases prior to 2001), running out of fuel on unscheduled routes, pilot errors (including inadequate flight training for new crews), and cargo fires; several accidents remain unexplained. The Tu-154 is described as having an average (or better than expected) safety record considering its length of service and heavy use in demanding conditions where other airliners are unable to operate.

It is the principal residence of the Dukes of Marlborough, and the only non-royal, non-episcopal country house in England to hold the title of palace. The palace, one of England's largest houses, was built between 1705 and 1722, and designated a UNESCO World Heritage Site in 1987. The palace is named for the 1704 Battle of Blenheim, and thus ultimately after Blindheim (also known as Blenheim) in Bavaria. It was originally intended to be a reward to John Churchill, 1st Duke of Marlborough for his

In response to complaints from the defenders of the Invalides perspective, the Public Services decided to shift the bridge site downriver. Therefore, in 1829, two engineers, de Verges and Bayard de la Vingtrie, completed the construction of a proper suspension bridge supported by two piers in the Seine and three porticos, each 20 m in height. Unfortunately, due to rapidly growing wear on the bridge, its access had to be regulated in 1850. In 1854, the bridge was

Paul-Martin Gallocher de Lagalisserie and Jules Savarin used the existing piers of the former suspension bridge and a newly added central pier to build an arch bridge in masonry on the same site. The new pier was adorned with sculptures in two allegorical themes: "the Land Victory" by Victor Vilain upriver; the Maritime Victory by Georges Diébolt downstream, whereas the two old piers were adorned with sculptures of military trophies bearing the imperial coat of arms, both the work of Astyanax-Scévola Bosio.

Instruction: Obtain documents that correspond to the inquiry alongside the provided image:

title: "Sea otter" content: Sea otter The sea otter ("Enhydra lutris") is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Adult sea otters typically weigh between , making them the heaviest members of the weasel family, but among the smallest marine mammals. Unlike most marine mammals, the sea otter's primary form of insulation is an exceptionally thick coat of fur, the densest in the animal kingdom. Although it can walk on land, the sea otter is capable of living exclusively in the ocean. The sea otter inhabits nearshore environments, where it dives to the sea floor to

title: "Sea otter" content: forage. It preys mostly on marine invertebrates such as sea urchins, various molluscs and crustaceans, and some species of fish. Its foraging and eating habits are noteworthy in several respects. First, its use of rocks to dislodge prey and to open shells makes it one of the few mammal species to use tools. In most of its range, it is a keystone species, controlling sea urchin populations which would otherwise inflict extensive damage to kelp forest ecosystems. Its diet includes prey species that are also valued by humans as food, leading to conflicts between sea otters and fisheries. Sea otters,

title: "Sea otter" content: whose numbers were once estimated at 150,000–300,000, were hunted extensively for their fur between 1741 and 1911, and the world population fell to 1,000–2,000 individuals living in a fraction of their historic range. A subsequent international ban on hunting, conservation efforts, and reintroduction programs into previously populated areas have contributed to numbers rebounding, and the species occupies about two-thirds of its former range. The recovery of the sea otter is considered an important success in marine conservation, although populations in the Aleutian Islands and California have recently declined or have plateaued at depressed levels. For these reasons, the sea otter

title: "Sea otter" content: remains classified as an endangered species. The sea otter is the heaviest (the giant otter is longer, but significantly slimmer) member of the family Mustelidae, a diverse group that includes the 13 otter species and terrestrial animals such as weasels, badgers, and minks. It is unique among the mustelids in not making or burrows, in having no functional anal scent glands, and in being able to live its entire life without leaving the water. The only member of the genus "Enhydra", the sea otter is so different from other mustelid species that, as recently as 1982, some scientists believed it

title: "Sea otter" content: was more closely related to the earless seals. Genetic analysis indicates the sea otter and its closest extant relatives, which include the African speckle-throated otter, European otter, African clawless otter and oriental small-clawed otter, shared an ancestor approximately 5 Mya (million years ago). Fossil evidence indicates the "Enhydra" lineage became isolated in the North Pacific approximately 2 Mya, giving rise to the now-extinct "Enhydra macrodonta" and the modern sea otter, "Enhydra lutris". One related species has been described, "Enhydra reevei", from the Pleistocene of East Anglia. The modern sea otter evolved initially in northern Hokkaidō and Russia, and then spread

title: "Sea otter" content: east to the Aleutian Islands, mainland Alaska, and down the North American coast. In comparison to cetaceans, sirenians, and pinnipeds, which entered the water approximately 50, 40, and 20 Mya, respectively, the sea otter is a relative newcomer to a marine existence. In some respects, though, the sea otter is more fully adapted to water than pinnipeds, which must haul out on land or ice to give birth. The full genome of the northern sea otter ("Enhydra lutris kenyoni") was sequenced in 2017 and may allow for examination of the sea otter's evolutionary divergence from terrestrial mustelids. The first scientific

title: "Sea otter" content: description of the sea otter is contained in the field notes of Georg Steller from 1751, and the species was described by Linnaeus in his "Systema Naturae" of 1758. Originally named "Lutra marina", it underwent numerous name changes before being accepted as "Enhydra lutris" in 1922. The generic name "Enhydra", derives from the Ancient Greek "en"/εν "in" and "hydra"/ύδρα "water", meaning "in the water", and the Latin word "lutris", meaning "otter". The sea otter was formerly sometimes referred to as the "sea beaver", being the marine fur-bearer similar in commercial value to the terrestrial beaver. Rodents (of which the beaver

title: "Sea otter" content: is one) are not closely related to otters, which are carnivorans. It is not to be confused with the marine otter, a rare otter species native to the southern west coast of South America. A number of other otter species, while predominantly living in fresh water, are commonly found in marine coastal habitats. The extinct sea mink of northeast North America is another mustelid that had adapted to a marine environment. Three subspecies of the sea otter are recognized with distinct geographical distributions. "Enhydra lutris lutris" (nominate), the Asian sea otter, ranges from the Kuril Islands north of Japan to

title: "Sea otter" content: Russia's Commander Islands in the western Pacific Ocean. In the eastern Pacific Ocean, "E. l. kenyoni", the northern sea otter, is found from Alaska's Aleutian Islands to Oregon and "E. l. nereis", the southern sea otter, is native to central and southern California. The Asian sea otter is the largest subspecies and has a slightly wider skull and shorter nasal bones than both other subspecies. Northern sea otters possess longer mandibles (lower jaws) while southern sea otters have longer rostrums and smaller teeth. The sea otter is one of the smallest marine mammal species, but it is the heaviest mustelid.

title: "Sea otter" content: Male sea otters usually weigh and are in length, though specimens up to have been recorded. Females are smaller, weighing and measuring in length. For its size, the male otter's baculum is very large, massive and bent upwards, measuring in length and at the base. Unlike most other marine mammals, the sea otter has no blubber and relies on its exceptionally thick fur to keep warm. With up to 150,000 strands of hair per square centimeter (nearly one million per sq in), its fur is the densest of any animal. The fur consists of long, waterproof guard hairs and short

title: "Sea otter" content: underfur; the guard hairs keep the dense underfur layer dry. Cold water is kept completely away from the skin and heat loss is limited. The fur is thick year-round, as it is shed and replaced gradually rather than in a distinct molting season. As the ability of the guard hairs to repel water depends on utmost cleanliness, the sea otter has the ability to reach and groom the fur on any part of its body, taking advantage of its loose skin and an unusually supple skeleton. The coloration of the pelage is usually deep brown with silver-gray speckles, but it

title: "Sea otter" content: can range from yellowish or grayish brown to almost black. In adults, the head, throat, and chest are lighter in color than the rest of the body. The sea otter displays numerous adaptations to its marine environment. The nostrils and small ears can close. The hind feet, which provide most of its propulsion in swimming, are long, broadly flattened, and fully webbed. The fifth digit on each hind foot is longest, facilitating swimming while on its back, but making walking difficult. The tail is fairly short, thick, slightly flattened, and muscular. The front paws are short with retractable claws, with

title: "Sea otter" content: tough pads on the palms that enable gripping slippery prey. The bones show osteosclerosis, increasing their density to reduce buoyancy. The sea otter propels itself underwater by moving the rear end of its body, including its tail and hind feet, up and down, and is capable of speeds of up to 9 km/h (5.6 mph). When underwater, its body is long and streamlined, with the short forelimbs pressed closely against the chest. When at the surface, it usually floats on its back and moves by sculling its feet and tail from side to side. At rest, all four limbs can

title: "Sea otter" content: be folded onto the torso to conserve heat, whereas on particularly hot days, the hind feet may be held underwater for cooling. The sea otter's body is highly buoyant because of its large lung capacity – about 2.5 times greater than that of similar-sized land mammals – and the air trapped in its fur. The sea otter walks with a clumsy, rolling gait on land, and can run in a bounding motion. Long, highly sensitive whiskers and front paws help the sea otter find prey by touch when waters are dark or murky. Researchers have noted when they approach in

title: "Sea otter" content: plain view, sea otters react more rapidly when the wind is blowing towards the animals, indicating the sense of smell is more important than sight as a warning sense. Other observations indicate the sea otter's sense of sight is useful above and below the water, although not as good as that of seals. Its hearing is neither particularly acute nor poor. An adult's 32 teeth, particularly the molars, are flattened and rounded for crushing rather than cutting food. Seals and sea otters are the only carnivores with two pairs of lower incisor teeth rather than three; the adult dental formula

title: "Sea otter" content: is The sea otter has a metabolic rate two or three times that of comparatively sized terrestrial mammals. It must eat an estimated 25 to 38% of its own body weight in food each day to burn the calories necessary to counteract the loss of heat due to the cold water environment. Its digestive efficiency is estimated at 80 to 85%, and food is digested and passed in as little as three hours. Most of its need for water is met through food, although, in contrast to most other marine mammals, it also drinks seawater. Its relatively large kidneys enable

title: "Sea otter" content: it to derive fresh water from sea water and excrete concentrated urine. The sea otter is diurnal. It has a period of foraging and eating in the morning, starting about an hour before sunrise, then rests or sleeps in mid-day. Foraging resumes for a few hours in the afternoon and subsides before sunset, and a third foraging period may occur around midnight. Females with pups appear to be more inclined to feed at night. Observations of the amount of time a sea otter must spend each day foraging range from 24 to 60%, apparently depending on the availability of food

title: "Sea otter" content: in the area. Sea otters spend much of their time grooming, which consists of cleaning the fur, untangling knots, removing loose fur, rubbing the fur to squeeze out water and introduce air, and blowing air into the fur. To casual observers, it appears as if the animals are scratching, but they are not known to have lice or other parasites in the fur. When eating, sea otters roll in the water frequently, apparently to wash food scraps from their fur. The sea otter hunts in short dives, often to the sea floor. Although it can hold its breath for up

title: "Sea otter" content: to five minutes, its dives typically last about one minute and not more than four. It is the only marine animal capable of lifting and turning over rocks, which it often does with its front paws when searching for prey. The sea otter may also pluck snails and other organisms from kelp and dig deep into underwater mud for clams. It is the only marine mammal that catches fish with its forepaws rather than with its teeth. Under each foreleg, the sea otter has a loose pouch of skin that extends across the chest. In this pouch (preferentially the left

title: "Sea otter" content: one), the animal stores collected food to bring to the surface. This pouch also holds a rock, unique to the otter, that is used to break open shellfish and clams. There, the sea otter eats while floating on its back, using its forepaws to tear food apart and bring it to its mouth. It can chew and swallow small mussels with their shells, whereas large mussel shells may be twisted apart. It uses its lower incisor teeth to access the meat in shellfish. To eat large sea urchins, which are mostly covered with spines, the sea otter bites through the

title: "Sea otter" content: underside where the spines are shortest, and licks the soft contents out of the urchin's shell. The sea otter's use of rocks when hunting and feeding makes it one of the few mammal species to use tools. To open hard shells, it may pound its prey with both paws against a rock on its chest. To pry an abalone off its rock, it hammers the abalone shell using a large stone, with observed rates of 45 blows in 15 seconds. Releasing an abalone, which can cling to rock with a force equal to 4,000 times its own body weight, requires

title: "Sea otter" content: multiple dives. Although each adult and independent juvenile forages alone, sea otters tend to rest together in single-sex groups called rafts. A raft typically contains 10 to 100 animals, with male rafts being larger than female ones. The largest raft ever seen contained over 2000 sea otters. To keep from drifting out to sea when resting and eating, sea otters may wrap themselves in kelp. A male sea otter is most likely to mate if he maintains a breeding territory in an area that is also favored by females. As autumn is the peak breeding season in most areas, males

title: "Sea otter" content: typically defend their territory only from spring to autumn. During this time, males patrol the boundaries of their territories to exclude other males, although actual fighting is rare. Adult females move freely between male territories, where they outnumber adult males by an average of five to one. Males that do not have territories tend to congregate in large, male-only groups, and swim through female areas when searching for a mate. The species exhibits a variety of vocal behaviors. The cry of a pup is often compared to that of a seagull. Females coo when they are apparently content; males may

title: "Sea otter" content: grunt instead. Distressed or frightened adults may whistle, hiss, or in extreme circumstances, scream. Although sea otters can be playful and sociable, they are not considered to be truly social animals. They spend much time alone, and each adult can meet its own needs in terms of hunting, grooming, and defense. Sea otters are polygynous: males have multiple female partners. However, temporary pair-bonding occurs for a few days between a female in estrus and her mate. Mating takes place in the water and can be rough, the male biting the female on the muzzle – which often leaves scars on

title: "Sea otter" content: the nose – and sometimes holding her head under water. Births occur year-round, with peaks between May and June in northern populations and between January and March in southern populations. Gestation appears to vary from four to twelve months, as the species is capable of delayed implantation followed by four months of pregnancy. In California, sea otters usually breed every year, about twice as often as those in Alaska. Birth usually takes place in the water and typically produces a single pup weighing 1.4 to 2.3 kg (3 to 5 lb). Twins occur in 2% of births; however, usually only

title: "Sea otter" content: one pup survives. At birth, the eyes are open, ten teeth are visible, and the pup has a thick coat of baby fur. Mothers have been observed to lick and fluff a newborn for hours; after grooming, the pup's fur retains so much air, the pup floats like a cork and cannot dive. The fluffy baby fur is replaced by adult fur after about 13 weeks. Nursing lasts six to eight months in Californian populations and four to twelve months in Alaska, with the mother beginning to offer bits of prey at one to two months. The milk from a

title: "Sea otter" content: sea otter's two abdominal nipples is rich in fat and more similar to the milk of other marine mammals than to that of other mustelids. A pup, with guidance from its mother, practices swimming and diving for several weeks before it is able to reach the sea floor. Initially, the objects it retrieves are of little food value, such as brightly colored starfish and pebbles. Juveniles are typically independent at six to eight months, but a mother may be forced to abandon a pup if she cannot find enough food for it; at the other extreme, a pup may nurse

title: "Sea otter" content: until it is almost adult size. Pup mortality is high, particularly during an individual's first winter – by one estimate, only 25% of pups survive their first year. Pups born to experienced mothers have the highest survival rates. Females perform all tasks of feeding and raising offspring, and have occasionally been observed caring for orphaned pups. Much has been written about the level of devotion of sea otter mothers for their pups – a mother gives her infant almost constant attention, cradling it on her chest away from the cold water and attentively grooming its fur. When foraging, she leaves

title: "Sea otter" content: her pup floating on the water, sometimes wrapped in kelp to keep it from floating away; if the pup is not sleeping, it cries loudly until she returns. Mothers have been known to carry their pups for days after the pups' deaths. Females become sexually mature at around three or four years of age and males at around five; however, males often do not successfully breed until a few years later. A captive male sired offspring at age 19. In the wild, sea otters live to a maximum age of 23 years, with average lifespans of 10–15 years for males

title: "Sea otter" content: and 15–20 years for females. Several captive individuals have lived past 20 years, and a female at the Seattle Aquarium died at the age of 28 years. Sea otters in the wild often develop worn teeth, which may account for their apparently shorter lifespans. There are several documented cases in which male sea otters have forcibly copulated with juvenile harbor seals, sometimes resulting in death. Similarly, forced copulation by sea otters involving animals other than Pacific harbor seals has occasionally been reported. Sea otters live in coastal waters 15 to 23 meters (50 to 75 ft) deep, and usually stay

title: "Sea otter" content: within a kilometer (⅔ mi) of the shore. They are found most often in areas with protection from the most severe ocean winds, such as rocky coastlines, thick kelp forests, and barrier reefs. Although they are most strongly associated with rocky substrates, sea otters can also live in areas where the sea floor consists primarily of mud, sand, or silt. Their northern range is limited by ice, as sea otters can survive amidst drift ice but not land-fast ice. Individuals generally occupy a home range a few kilometers long, and remain there year-round. The sea otter population is thought to

title: "Sea otter" content: have once been 150,000 to 300,000, stretching in an arc across the North Pacific from northern Japan to the central Baja California Peninsula in Mexico. The fur trade that began in the 1740s reduced the sea otter's numbers to an estimated 1,000 to 2,000 members in 13 colonies. In about two-thirds of its former range, the species is at varying levels of recovery, with high population densities in some areas and threatened populations in others. Sea otters currently have stable populations in parts of the Russian east coast, Alaska, British Columbia, Washington, and California, with reports of recolonizations in Mexico

title: "Sea otter" content: and Japan. Population estimates made between 2004 and 2007 give a worldwide total of approximately 107,000 sea otters. Currently, the most stable and secure part of the sea otter's range is Russia. Before the 19th century, around 20,000 to 25,000 sea otters lived near the Kuril Islands, with more near Kamchatka and the Commander Islands. After the years of the Great Hunt, the population in these areas, currently part of Russia, was only 750. By 2004, sea otters had repopulated all of their former habitat in these areas, with an estimated total population of about 27,000. Of these, about 19,000

title: "Sea otter" content: are at the Kurils, 2,000 to 3,500 at Kamchatka and another 5,000 to 5,500 at the Commander Islands. Growth has slowed slightly, suggesting the numbers are reaching carrying capacity. Alaska is the heartland of the sea otter's range. In 1973, the population in Alaska was estimated at between 100,000 and 125,000 animals. By 2006, though, the Alaska population had fallen to an estimated 73,000 animals. A massive decline in sea otter populations in the Aleutian Islands accounts for most of the change; the cause of this decline is not known, although orca predation is suspected. The sea otter population in

title: "Sea otter" content: Prince William Sound was also hit hard by the Exxon Valdez oil spill, which killed thousands of sea otters in 1989. Along the North American coast south of Alaska, the sea otter's range is discontinuous. A remnant population survived off Vancouver Island into the 20th century, but it died out despite the 1911 international protection treaty, with the last sea otter taken near Kyuquot in 1929. From 1969 to 1972, 89 sea otters were flown or shipped from Alaska to the west coast of Vancouver Island. This population increased to over 5,600 in 2013 with an estimated annual growth rate

title: "Sea otter" content: of 7.2%, and their range on the island's west coast extended north to Cape Scott and across the Queen Charlotte Straight to the Broughton Archipelago and south to Clayoquot Sound and Tofino. In 1989, a separate colony was discovered in the central British Columbia coast. It is not known if this colony, which numbered about 300 animals in 2004, was founded by transplanted otters or was a remnant population that had gone undetected. By 2013, this population exceeded 1,100 individuals, was increasing at an estimated 12.6% annual rate, and its range included Aristazabal Island, and Milbanke Sound south to Calvert

title: "Sea otter" content: Island. In 2008, Canada determined the status of sea otters to be "special concern". In 1969 and 1970, 59 sea otters were translocated from Amchitka Island to Washington, and released near La Push and Point Grenville. The translocated population is estimated to have declined to between 10 and 43 individuals before increasing, reaching 208 individuals in 1989. As of 2017, the population was estimated at over 2,000 individuals, and their range extends from Point Grenville in the south to Cape Flattery in the north and east to Pillar Point along the Strait of Juan de Fuca. In Washington, sea otters

title: "Sea otter" content: are found almost exclusively on the outer coasts. They can swim as close as six feet off shore along the Olympic coast. Reported sightings of sea otters in the San Juan Islands and Puget Sound almost always turn out to be North American river otters, which are commonly seen along the seashore. However, biologists have confirmed isolated sightings of sea otters in these areas since the mid-1990s. The last native sea otter in Oregon was probably shot and killed in 1906. In 1970 and 1971, a total of 95 sea otters were transplanted from Amchitka Island, Alaska to the Southern

title: "Sea otter" content: Oregon coast. However, this translocation effort failed and otters soon again disappeared from the state. In 2004, a male sea otter took up residence at Simpson Reef off of Cape Arago for six months. This male is thought to have originated from a colony in Washington, but disappeared after a coastal storm. On 18 February 2009, a male sea otter was spotted in Depoe Bay off the Oregon Coast. It could have traveled to the state from either California or Washington. The historic population of California sea otters was estimated at 16,000 before the fur trade decimated the population, leading

title: "Sea otter" content: to their assumed extinction. Today's population of California sea otters are the descendants of a single colony of about 50 sea otters located near Bixby Creek Bridge in March 1938 by Howard G. Sharpe, owner of the nearby Rainbow Lodge on Bixby Bridge in Big Sur. Their principal range has gradually expanded and extends from Pigeon Point in San Mateo County to Santa Barbara County. Sea otters were once numerous in San Francisco Bay. Historical records revealed the Russian-American Company sneaked Aleuts into San Francisco Bay multiple times, despite the Spanish capturing or shooting them while hunting sea otters in

title: "Sea otter" content: the estuaries of San Jose, San Mateo, San Bruno and around Angel Island. The founder of Fort Ross, Ivan Kuskov, finding otters scarce on his second voyage to Bodega Bay in 1812, sent a party of Aleuts to San Francisco Bay, where they met another Russian party and an American party, and caught 1,160 sea otters in three months. By 1817, sea otters in the area were practically eliminated and the Russians sought permission from the Spanish and the Mexican governments to hunt further and further south of San Francisco. Remnant sea otter populations may have survived in the bay

title: "Sea otter" content: until 1840, when the Rancho Punta de Quentin was granted to Captain John B. R. Cooper, a sea captain from Boston, by Mexican Governor Juan Bautista Alvarado along with a license to hunt sea otters, reportedly then prevalent at the mouth of Corte Madera Creek. In the late 1980s, the USFWS relocated about 140 southern sea otters to San Nicolas Island in southern California, in the hope of establishing a reserve population should the mainland be struck by an oil spill. To the surprise of biologists, the majority of the San Nicolas sea otters swam back to the mainland. Another

title: "Sea otter" content: group of twenty swam north to San Miguel Island, where they were captured and removed. By 2005, only 30 sea otters remained at San Nicolas, although they were slowly increasing as they thrived on the abundant prey around the island. The plan that authorized the translocation program had predicted the carrying capacity would be reached within five to 10 years. The spring 2016 count at San Nicolas Island was 104 sea otters, continuing a 5-year positive trend of over 12% per year. Sea otters were observed twice in Southern California in 2011, once near Laguna Beach and once at Zuniga

title: "Sea otter" content: Point Jetty, near San Diego. These are the first documented sightings of otters this far south in 30 years. When the USFWS implemented the translocation program, it also attempted to implement "zonal management" of the Californian population. To manage the competition between sea otters and fisheries, it declared an "otter-free zone" stretching from Point Conception to the Mexican border. In this zone, only San Nicolas Island was designated as sea otter habitat, and sea otters found elsewhere in the area were supposed to be captured and relocated. These plans were abandoned after many translocated otters died and also as it

title: "Sea otter" content: proved impractical to capture the hundreds of otters which ignored regulations and swam into the zone. However, after engaging in a period of public commentary in 2005, the Fish and Wildlife Service failed to release a formal decision on the issue. Then, in response to lawsuits filed by the Santa Barbara-based Environmental Defense Center and the Otter Project, on 19 December 2012 the USFWS declared that the "no otter zone" experiment was a failure, and will protect the otters re-colonizing the coast south of Point Conception as threatened species. Although abalone fisherman blamed the incursions of sea otters for the

title: "Sea otter" content: decline of abalone, commercial abalone fishing in southern California came to an end from overfishing in 1997, years before significant otter moved south of Point Conception. In addition, white abalone ("Haliotis sorenseni"), a species never overlapping with sea otter, had declined in numbers 99% by 1996, and became the first marine invertebrate to be federally listed as endangered. Although the southern sea otter's range has continuously expanded from the remnant population of about 50 individuals in Big Sur since protection in 1911, from 2007 to 2010, the otter population and its range contracted and since 2010 has made little progress.

title: "Sea otter" content: As of spring 2010, the northern boundary had moved from about Tunitas Creek to a point 2 km southeast of Pigeon Point, and the southern boundary has moved from approximately Coal Oil Point to Gaviota State Park. Recently, a toxin called microcystin, produced by a type of cyanobacteria ("Microcystis"), seems to be concentrated in the shellfish the otters eat, poisoning them. Cyanobacteria are found in stagnant freshwater enriched with nitrogen and phosphorus from septic tank and agricultural fertilizer runoff, and may be flushed into the ocean when streamflows are high in the rainy season. A record number of sea otter

title: "Sea otter" content: carcasses were found on California's coastline in 2010, with increased shark attacks an increasing component of the mortality. Great white sharks do not consume relatively fat-poor sea otters but shark-bitten carcasses have increased from 8% in the 1980s to 15% in the 1990s and to 30% in 2010 and 2011. For southern sea otters to be considered for removal from threatened species listing, the U.S. Fish and Wildlife Service (USFWS) determined that the population should exceed 3,090 for three consecutive years. In response to recovery efforts, the population climbed steadily from the mid-20th century through the early 2000s, then remained

title: "Sea otter" content: relatively flat from 2005 to 2014 at just under 3,000. There was some contraction from the northern (now Pigeon Point) and southern limits of the sea otter's range during the end of this period, circumstantially related to an increase in lethal shark bites, raising concerns that the population had reached a plateau. However, the population increased markedly from 2015 to 2016, with the United States Geological Survey (USGS) California sea otter survey 3-year average reaching 3,272 in 2016, the first time it exceeded the threshold for delisting from the Endangered Species Act (ESA). If populations continued to grow and ESA

title: "Sea otter" content: delisting occurred, southern sea otters would still be fully protected by state regulations and the Marine Mammal Protection Act, which set higher thresholds for protection, at approximately 8,400 individuals. However, ESA delisting seems unlikely due to a precipitous population decline recorded in the spring 2017 USGS sea otter survey count, from the 2016 high of 3,615 individuals to 2,688, a loss of 25% of the California sea otter population. Sea otters consume over 100 prey species. In most of its range, the sea otter's diet consists almost exclusively of marine benthic invertebrates, including sea urchins, fat innkeeper worms, a variety

title: "Sea otter" content: of bivalves such as clams and mussels, abalone, other mollusks, crustaceans, and snails. Its prey ranges in size from tiny limpets and crabs to giant octopuses. Where prey such as sea urchins, clams, and abalone are present in a range of sizes, sea otters tend to select larger items over smaller ones of similar type. In California, they have been noted to ignore Pismo clams smaller than 3 inches (7 cm) across. In a few northern areas, fish are also eaten. In studies performed at Amchitka Island in the 1960s, where the sea otter population was at carrying capacity, 50%

title: "Sea otter" content: of food found in sea otter stomachs was fish. The fish species were usually bottom-dwelling and sedentary or sluggish forms, such as "Hemilepidotus hemilepidotus" and family Tetraodontidae. However, south of Alaska on the North American coast, fish are a negligible or extremely minor part of the sea otter's diet. Contrary to popular depictions, sea otters rarely eat starfish, and any kelp that is consumed apparently passes through the sea otter's system undigested. The individuals within a particular area often differ in their foraging methods and prey types, and tend to follow the same patterns as their mothers. The diet of

title: "Sea otter" content: local populations also changes over time, as sea otters can significantly deplete populations of highly preferred prey such as large sea urchins, and prey availability is also affected by other factors such as fishing by humans. Sea otters can thoroughly remove abalone from an area except for specimens in deep rock crevices, however, they never completely wipe out a prey species from an area. A 2007 Californian study demonstrated, in areas where food was relatively scarce, a wider variety of prey was consumed. Surprisingly, though, the diets of individuals were more specialized in these areas than in areas where food

title: "Sea otter" content: was plentiful. Sea otters are a classic example of a keystone species; their presence affects the ecosystem more profoundly than their size and numbers would suggest. They keep the population of certain benthic (sea floor) herbivores, particularly sea urchins, in check. Sea urchins graze on the lower stems of kelp, causing the kelp to drift away and die. Loss of the habitat and nutrients provided by kelp forests leads to profound cascade effects on the marine ecosystem. North Pacific areas that do not have sea otters often turn into urchin barrens, with abundant sea urchins and no kelp forest. Kelp

title: "Sea otter" content: forests are extremely productive ecosystems. Kelp forests sequester (absorb and capture) CO2 from the atmosphere through photosynthesis. Sea otters may help mitigate effects of climate change by their cascading trophic influence Reintroduction of sea otters to British Columbia has led to a dramatic improvement in the health of coastal ecosystems, and similar changes have been observed as sea otter populations recovered in the Aleutian and Commander Islands and the Big Sur coast of California However, some kelp forest ecosystems in California have also thrived without sea otters, with sea urchin populations apparently controlled by other factors. The role of sea

title: "Sea otter" content: otters in maintaining kelp forests has been observed to be more important in areas of open coast than in more protected bays and estuaries. Sea otters effect rocky ecosystems that are dominated by mussel beds by removing mussels from rocks. This allows space for competing species and increases species diversity. Leading mammalian predators of this species include orcas and sea lions, and bald eagles may grab pups from the surface of the water. Young predators may kill an otter and not eat it. On land, young sea otters may face attack from bears and coyotes. In California, great white sharks

title: "Sea otter" content: are their primary predator but there is no evidence that the sharks eat them. Urban runoff transporting cat feces into the ocean brings "Toxoplasma gondii", an obligate parasite, which has killed sea otters. Parasitic infections of "Sarcocystis neurona" are also associated with human activity. According to the U.S. Geological Survey and the CDC, northern sea otters off Washington have been infected with the H1N1 flu virus and "may be a newly identified animal host of influenza viruses". Sea otters have the thickest fur of any mammal. Their beautiful fur is a main target for many hunters. Archaeological evidence indicates that

title: "Sea otter" content: for thousands of years, indigenous peoples have hunted sea otters for food and fur. Large-scale hunting, part of the Maritime Fur Trade, which would eventually kill approximately one million sea otters, began in the 18th century when hunters and traders began to arrive from all over the world to meet foreign demand for otter pelts, which were one of the world's most valuable types of fur. In the early 18th century, Russians began to hunt sea otters in the Kuril Islands and sold them to the Chinese at Kyakhta. Russia was also exploring the far northern Pacific at this time,

title: "Sea otter" content: and sent Vitus Bering to map the Arctic coast and find routes from Siberia to North America. In 1741, on his second North Pacific voyage, Bering was shipwrecked off Bering Island in the Commander Islands, where he and many of his crew died. The surviving crew members, which included naturalist Georg Steller, discovered sea otters on the beaches of the island and spent the winter hunting sea otters and gambling with otter pelts. They returned to Siberia, having killed nearly 1,000 sea otters, and were able to command high prices for the pelts. Thus began what is sometimes called the

title: "Sea otter" content: "Great Hunt", which would continue for another hundred years. The Russians found the sea otter far more valuable than the sable skins that had driven and paid for most of their expansion across Siberia. If the sea otter pelts brought back by Bering's survivors had been sold at Kyakhta prices they would have paid for one tenth the cost of Bering's expedition. In 1775 at Okhotsk, sea otter pelts were worth 50–80 rubles as opposed to 2.5 rubles for sable. Russian fur-hunting expeditions soon depleted the sea otter populations in the Commander Islands, and by 1745, they began to move

title: "Sea otter" content: on to the Aleutian Islands. The Russians initially traded with the Aleuts inhabitants of these islands for otter pelts, but later enslaved the Aleuts, taking women and children hostage and torturing and killing Aleut men to force them to hunt. Many Aleuts were either murdered by the Russians or died from diseases the hunters had introduced. The Aleut population was reduced, by the Russians' own estimate, from 20,000 to 2,000. By the 1760s, the Russians had reached Alaska. In 1799, Emperor Paul I consolidated the rival fur-hunting companies into the Russian-American Company, granting it an imperial charter and protection, and

title: "Sea otter" content: a monopoly over trade rights and territorial acquisition. Under Aleksandr I, the administration of the merchant-controlled company was transferred to the Imperial Navy, largely due to the alarming reports by naval officers of native abuse; in 1818, the indigenous peoples of Alaska were granted civil rights equivalent to a townsman status in the Russian Empire. Other nations joined in the hunt in the south. Along the coasts of what is now Mexico and California, Spanish explorers bought sea otter pelts from Native Americans and sold them in Asia. In 1778, British explorer Captain James Cook reached Vancouver Island and bought

title: "Sea otter" content: sea otter furs from the First Nations people. When Cook's ship later stopped at a Chinese port, the pelts rapidly sold at high prices, and were soon known as "soft gold". As word spread, people from all over Europe and North America began to arrive in the Pacific Northwest to trade for sea otter furs. Russian hunting expanded to the south, initiated by American ship captains, who subcontracted Russian supervisors and Aleut hunters in what are now Washington, Oregon, and California. Between 1803 and 1846, 72 American ships were involved in the otter hunt in California, harvesting an estimated 40,000

title: "Sea otter" content: skins and tails, compared to only 13 ships of the Russian-American Company, which reported 5,696 otter skins taken between 1806 and 1846. In 1812, the Russians founded an agricultural settlement at what is now Fort Ross in northern California, as their southern headquarters. Eventually, sea otter populations became so depleted, commercial hunting was no longer viable. It had stopped in the Aleutian Islands, by 1808, as a conservation measure imposed by the Russian-American Company. Further restrictions were ordered by the Company in 1834. When Russia sold Alaska to the United States in 1867, the Alaska population had recovered to over

title: "Sea otter" content: 100,000, but Americans resumed hunting and quickly extirpated the sea otter again. Prices rose as the species became rare. During the 1880s, a pelt brought $105 to $165 in the London market, but by 1903, a pelt could be worth as much as $1,125. In 1911, Russia, Japan, Great Britain (for Canada) and the United States signed the Treaty for the Preservation and Protection of Fur Seals, imposing a moratorium on the harvesting of sea otters. So few remained, perhaps only 1,000–2,000 individuals in the wild, that many believed the species would become extinct. During the 20th century, sea otter

title: "Sea otter" content: numbers rebounded in about two-thirds of their historic range, a recovery considered one of the greatest successes in marine conservation. However, the IUCN still lists the sea otter as an endangered species, and describes the significant threats to sea otters as oil pollution, predation by orcas, poaching, and conflicts with fisheries – sea otters can drown if entangled in fishing gear. The hunting of sea otters is no longer legal except for limited harvests by indigenous peoples in the United States. Poaching was a serious concern in the Russian Far East immediately after the collapse of the Soviet Union in

title: "Sea otter" content: 1991; however, it has declined significantly with stricter law enforcement and better economic conditions. The most significant threat to sea otters is oil spills, to which they are particularly vulnerable, since they rely on their fur to keep warm. When their fur is soaked with oil, it loses its ability to retain air, and the animals can quickly die from hypothermia. The liver, kidneys, and lungs of sea otters also become damaged after they inhale oil or ingest it when grooming. The Exxon Valdez oil spill of 24 March 1989 killed thousands of sea otters in Prince William Sound, and

title: "Sea otter" content: as of 2006, the lingering oil in the area continues to affect the population. Describing the public sympathy for sea otters that developed from media coverage of the event, a U.S. Fish and Wildlife Service spokesperson wrote: The small geographic ranges of the sea otter populations in California, Washington, and British Columbia mean a single major spill could be catastrophic for that state or province. Prevention of oil spills and preparation to rescue otters if one happens is a major focus for conservation efforts. Increasing the size and range of sea otter populations would also reduce the risk of an

title: "Sea otter" content: oil spill wiping out a population. However, because of the species' reputation for depleting shellfish resources, advocates for commercial, recreational, and subsistence shellfish harvesting have often opposed allowing the sea otter's range to increase, and there have even been instances of fishermen and others illegally killing them. In the Aleutian Islands, a massive and unexpected disappearance of sea otters has occurred in recent decades. In the 1980s, the area was home to an estimated 55,000 to 100,000 sea otters, but the population fell to around 6,000 animals by 2000. The most widely accepted, but still controversial, hypothesis is that killer

title: "Sea otter" content: whales have been eating the otters. The pattern of disappearances is consistent with a rise in predation, but there has been no direct evidence of orcas preying on sea otters to any significant extent. Another area of concern is California, where recovery began to fluctuate or decline in the late 1990s. Unusually high mortality rates amongst adult and subadult otters, particularly females, have been reported. In 2017 the US Geological Survey found a 3% drop in the sea otter population of the California coast. This number still keeps them on track for removal from the endangered species list, although just

title: "Sea otter" content: barely. Necropsies of dead sea otters indicate diseases, particularly "Toxoplasma gondii" and acanthocephalan parasite infections, are major causes of sea otter mortality in California. The "Toxoplasma gondii" parasite, which is often fatal to sea otters, is carried by wild and domestic cats and may be transmitted by domestic cat droppings flushed into the ocean via sewage systems. Although disease has clearly contributed to the deaths of many of California's sea otters, it is not known why the California population is apparently more affected by disease than populations in other areas. Sea otter habitat is preserved through several protected areas in

title: "Sea otter" content: the United States, Russia and Canada. In marine protected areas, polluting activities such as dumping of waste and oil drilling are typically prohibited. An estimated 1,200 sea otters live within the Monterey Bay National Marine Sanctuary, and more than 500 live within the Olympic Coast National Marine Sanctuary. Some of the sea otter's preferred prey species, particularly abalone, clams, and crabs, are also food sources for humans. In some areas, massive declines in shellfish harvests have been blamed on the sea otter, and intense public debate has taken place over how to manage the competition between sea otters and humans

title: "Sea otter" content: for seafood. The debate is complicated because sea otters have sometimes been held responsible for declines of shellfish stocks that were more likely caused by overfishing, disease, pollution, and seismic activity. Shellfish declines have also occurred in many parts of the North American Pacific coast that do not have sea otters, and conservationists sometimes note the existence of large concentrations of shellfish on the coast is a recent development resulting from the fur trade's near-extirpation of the sea otter. Although many factors affect shellfish stocks, sea otter predation can deplete a fishery to the point where it is no longer

title: "Sea otter" content: commercially viable. Scientists agree that sea otters and abalone fisheries cannot exist in the same area, and the same is likely true for certain other types of shellfish, as well. Many facets of the interaction between sea otters and the human economy are not as immediately felt. Sea otters have been credited with contributing to the kelp harvesting industry via their well-known role in controlling sea urchin populations; kelp is used in the production of diverse food and pharmaceutical products. Although human divers harvest red sea urchins both for food and to protect the kelp, sea otters hunt more sea

title: "Sea otter" content: urchin species and are more consistently effective in controlling these populations. The health of the kelp forest ecosystem is significant in nurturing populations of fish, including commercially important fish species. In some areas, sea otters are popular tourist attractions, bringing visitors to local hotels, restaurants, and sea otter-watching expeditions. For many maritime indigenous cultures throughout the North Pacific, especially the Ainu in the Kuril Islands, the Koryaks and Itelmen of Kamchatka, the Aleut in the Aleutian Islands, the Haida of Haida Gwaii and a host of tribes on the Pacific coast of North America, the sea otter has played an

title: "Sea otter" content: important role as a cultural, as well as material, resource. In these cultures, many of which have strongly animist traditions full of legends and stories in which many aspects of the natural world are associated with spirits, the sea otter was considered particularly kin to humans. The Nuu-chah-nulth, Haida, and other First Nations of coastal British Columbia used the warm and luxurious pelts as chiefs' regalia. Sea otter pelts were given in potlatches to mark coming-of-age ceremonies, weddings, and funerals. The Aleuts carved sea otter bones for use as ornaments and in games, and used powdered sea otter baculum as

title: "Sea otter" content: a medicine for fever. Among the Ainu, the otter is portrayed as an occasional messenger between humans and the creator. The sea otter is a recurring figure in Ainu folklore. A major Ainu epic, the "Kutune Shirka", tells the tale of wars and struggles over a golden sea otter. Versions of a widespread Aleut legend tell of lovers or despairing women who plunge into the sea and become otters. These links have been associated with the many human-like behavioral features of the sea otter, including apparent playfulness, strong mother-pup bonds and tool use, yielding to ready anthropomorphism. The beginning of

title: "Sea otter" content: commercial exploitation had a great impact on the human, as well as animal, populations the Ainu and Aleuts have been displaced or their numbers are dwindling, while the coastal tribes of North America, where the otter is in any case greatly depleted, no longer rely as intimately on sea mammals for survival. Since the mid-1970s, the beauty and charisma of the species have gained wide appreciation, and the sea otter has become an icon of environmental conservation. The round, expressive face and soft, furry body of the sea otter are depicted in a wide variety of souvenirs, postcards, clothing, and

title: "Sea otter" content: stuffed toys. Sea otters can do well in captivity, and are featured in over 40 public aquariums and zoos. The Seattle Aquarium became the first institution to raise sea otters from conception to adulthood with the birth of Tichuk in 1979, followed by three more pups in the early 1980s. In 2007, a YouTube video of two sea otters holding paws drew 1.5 million viewers in two weeks, and had over 20 million views . Filmed five years previously at the Vancouver Aquarium, it was YouTube's most popular animal video at the time, although it has since been surpassed. The
