Does a fin whale have teeth?
The fin whale can reach up to 85 feet in length and between 40 and 80 tons in weight. They are baleen whales, which means they don’t have teeth, but baleen plates – comb-like structures made of keratin like our hair and nails.
How many teeth does a fin whale have?
Instead of teeth, the typical fin whale has around 260 to 480 baleen plates on each side of its mouth for filtering out food from the water.
How do rorquals feed?
Like all baleen whales, rorquals are suspension filter feeders that separate small crustaceans and fish from engulfed water using plates of keratin—the same protein that forms hair, fingernails and turtle shells—that hang down from the top of their mouths.
What prevents whales from choking?
A recent study by Gil et al. dissected deceased fin whales and discovered an anatomical structure that seems to be making the lunge-feeding and no choking process possible. Coined “oral plug” in the study, this large musculo-fatty structure passively seals the oropharyngeal channel and is not observed in other animals.
Which whale has no teeth?
Baleen whales do not have teeth. Baleen whales have two blowholes, and they tend to be larger than toothed whales. Instead of teeth, whales in this group have special baleen plates with bristles that serve their dental needs.
Do fin whales eat dolphins?
In the North Atlantic, they are often seen feeding in large groups that include humpback whales, minke whales, and Atlantic white-sided dolphins.
How do fin whales eat?
Like other baleen whales, fin whales have expandable pleats that allow them to take in huge amounts of water and food. They then sieve the water out through their baleen plates before ingesting their delicious meal, consuming up to 2,000kg of krill in a day.
Do whales eat jellyfish?
Generally, jellyfish get sucked right into the mouths of whales due to their soft and squishy, gelatinous bodies and are digested easily as well. Hence, jellyfish make easy prey for whales like several other animals.
What does a rorqual look like?
Rorquals are slender and streamlined in shape, compared with their relatives the right whales, and most have narrow, elongated flippers. They have a dorsal fin, situated about two-thirds the way back.
Can a whale swallow a human?
Despite occasional reports of whales scooping people into their mouths, it’s incredibly rare—and for all but one species, swallowing a human is physically impossible.
Do whales have nipples?
Whales and dolphins do not have external nipples, instead their nipples are enclosed within mammary slits. Upon stimulation of the calves nudging, the nipple is exposed and the calf positions itself such that the nipple is at the gape of the calf’s jaw for feeding.
Are all whales toothless?
There are actually two different suborders of whales that are distinguished by their presence or lacking presence of teeth: Baleen whales and toothed whales. Baleen whales and toothed whales are very different on multiple levels including their species size, blowholes and biology, how they feed, and more.
Are fin whales friendly?
Even though fairly shy and reserved when it comes to showing off their unique tail flukes and acrobatic breaching skills, fin whales are often very friendly with boats.

Do sharks eat whales?
Sharks are known for their sharp teeth and incredible hunting abilities. They might look like sweethearts, but sharks don’t generally eat whales. However, there have been several documented instances of whale sharks being eaten by tiger sharks.
What can a rorqual jump to?
The Rorqual has a few new capabilities:
- Bridge mining ships like a titan can do.
- Conduit Jump mining ships like a black ops battleship can do.
- Jump or Bridge to an Industrial Cyno Beacon.
Why do whales have pleats?
Blue Whale (Suborder: Mysticeti) The blue whale, like the humpback, has ventral pleats—creases that run vertically down the underside of a whale’s jaw all the way to its stomach. When feeding, the ventral pleats expand like an accordion to accommodate ahuge amount of food-rich water.
