Scaphirhynchus is a genus of sturgeons native to the ___MASK51___ . All species in this genus are considered to be threatened . The pallid sturgeon is Endangered and the Alabama sturgeon is Critically Endangered . The Triassic is a geologic period and system which spans 50 . 9 million years from the end of the Permian Period million years ago ( Mya ), to the beginning of the Jurassic Period Mya . The Triassic is the first period of the Mesozoic Era . Both the start and end of the period are marked by major extinction events . The Triassic was named in 1834 by Friedrich von Alberti , after the three distinct rock layers (" tri " meaning " three ") that are found throughout ___MASK62___ and northwestern Europe  red beds , capped by marine limestone , followed by a series of terrestrial mud - and sandstones  called the " Trias ". Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae . Their evolution dates back to the Triassic some 245 to 208 million years ago . The family is grouped into four genera : " Acipenser ", " Huso ", " Scaphirhynchus " and " Pseudoscaphirhynchus ". Four species may now be extinct . Two closely related species , " Polyodon spathula " ( paddlefish ) and " Psephurus gladius " ( ___MASK76___ paddlefish , possibly extinct ) are of the same order , Acipenseriformes , but are in the family Polyodontidae and are not considered to be " true " sturgeons . Both sturgeons and paddlefish have been referred to as " primitive fishes " because their morphological characteristics have remained relatively unchanged since the earliest fossil record . Sturgeons are native to subtropical , temperate and sub - Arctic rivers , lakes and coastlines of Eurasia and North America . Sturgeons are long - lived , late - maturing fishes with distinctive characteristics , such as a heterocercal caudal fin similar to that of sharks , and an elongated spindle - like body that is smooth - skinned , scaleless and armored with 5 lateral rows of bony plates called scutes . Several species can grow quite large , typically ranging 7  12 feet ( 2 - 3 m ) in length . The largest sturgeon on record was a Beluga female captured in the Volga estuary in 1827 , weighing and long . Most sturgeons are anadromous bottom - feeders which migrate upstream to spawn but spend most of their lives feeding in river deltas and estuaries . Some species inhabit freshwater environments exclusively while others primarily inhabit marine environments near coastal areas , and are known to venture into open ocean . North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere . It can also be considered a northern subcontinent of the Americas . It is bordered to the north by the Arctic Ocean , to the east by the ___MASK98___ , to the west and south by the Pacific Ocean , and to the southeast by South America and the Caribbean Sea . Eurasia is the combined continental landmass of Europe and Asia . The term is a portmanteau of its constituent continents . Located primarily in the Northern and Eastern Hemispheres , it is bordered by the ___MASK98___ to the west , the Pacific Ocean to the east , the Arctic Ocean to the north , and by Africa , the Mediterranean Sea , and the Indian Ocean to the south . The division between Europe and Asia as two different continents is a historical and cultural construct , with no clear physical separation between them ; thus , in some parts of the world , Eurasia is recognized as the largest of five or six continents . In geology , Eurasia is often considered as a single rigid megablock . However , the rigidity of Eurasia is debated based on the paleomagnet data . The United Nations ( UN ) is an intergovernmental organization to promote international co - operation . A replacement for the ineffective League of Nations , the organization was established on 24 October 1945 after ___MASK5___ War II in order to prevent another such conflict . At its founding , the UN had 51 member states ; there are now 193 . The headquarters of the United Nations is in Manhattan , New York City , and experiences extraterritoriality . Further main offices are situated in Geneva , ___MASK46___ , and Vienna . The organization is financed by assessed and voluntary contributions from its member states . Its objectives include maintaining international peace and security , promoting human rights , fostering social and economic development , protecting the environment , and providing humanitarian aid in cases of famine , natural disaster , and armed conflict . Michigan is a state in the Great Lakes and Midwestern regions of the ___MASK90___ . The name Michigan is the French form of the Ojibwa word " mishigamaa ", meaning " large water " or " large lake ". Michigan is the tenth most populous of the 50 ___MASK90___ , with the 11th most extensive total area ( the largest state by total area east of the Mississippi River ). Its capital is Lansing , and its largest city is Detroit . A U . S . state is a constituent political entity of the ___MASK51___ . There are 50 states , which are bound together in a union with each other . Each state holds administrative jurisdiction over a defined geographic territory , and shares its sovereignty with the United States federal government . Due to the shared sovereignty between each state and the federal government , Americans are citizens of both the federal republic and of the state in which they reside . State citizenship and residency are flexible , and no government approval is required to move between states , except for persons covered by certain types of court orders ( e . g ., paroled convicts and children of divorced spouses who are sharing custody ). Onaway is a city in Presque Isle County in the U . S . state of Michigan . The population was 880 at the 2010 census . Onaway is the Sturgeon Capital of Michigan . The Great Lakes ( also called the Laurentian Great Lakes , or the Great Lakes of North America ) are a series of interconnected freshwater lakes located primarily in the upper mid - east region of North America , on the ___MASK56___  United States border , which connect to the ___MASK98___ through the Saint Lawrence River . Consisting of Lakes Superior , Michigan , Huron ( or Michigan  Huron ), Erie , and Ontario , they form the largest group of freshwater lakes on Earth , containing 21 % of the world ' s surface fresh water by volume . The total surface is , and the total volume ( measured at the low water datum ) is . Due to their sea - like characteristics ( rolling waves , sustained winds , strong currents , great depths , and distant horizons ) the five Great Lakes have also long been referred to as " inland seas ". Lake Superior is the second largest lake in the world by area , and Lake Michigan is the largest lake that is entirely within one country . The southern half of the Great Lakes is bordered by the Great Lakes Megalopolis . A census is the procedure of systematically acquiring and recording information about the members of a given population . It is a regularly occurring and official count of a particular population . The term is used mostly in connection with national population and housing censuses ; other common censuses include agriculture , business , and traffic censuses . The United Nations defines the essential features of population and housing censuses as " individual enumeration , universality within a defined territory , simultaneity and defined periodicity ", and recommends that population censuses be taken at least every 10 years . United Nations recommendations also cover census topics to be collected , official definitions , classifications and other useful information to co - ordinate international practice . Detroit is the most populous city in the U . S . state of Michigan , the fourth - largest city in the Midwest and the largest city on the ___MASK90___  ___MASK56___ border . It is the seat of Wayne County , the most populous county in the state . The Mississippi River is the chief river of the largest drainage system on the North American continent . Flowing entirely in the ___MASK90___ ( although its drainage basin reaches into ___MASK56___ ), it rises in northern Minnesota and meanders slowly southwards for to the Mississippi River Delta at the Gulf of Mexico . With its many tributaries , the Mississippi ' s watershed drains all or parts of 31 U . S . states and 2 Canadian provinces between the Rocky and Appalachian Mountains . The Mississippi ranks as the fourth longest and fifteenth largest river in the world by discharge . The river either borders or passes through the states of Minnesota , Wisconsin , Iowa , Illinois , Missouri , Kentucky , Tennessee , Arkansas , Mississippi , and Louisiana . Americans are citizens of the ___MASK51___ . The country is home to people of many different national origins . As a result , Americans do not equate their nationality with ethnicity , but with citizenship and allegiance . Although citizens make up the majority of Americans , non - citizen residents , dual citizens , and expatriates may also claim an American identity .
