What are the characteristics of a baleen whale?
Coloration. Most baleen whales exhibit skin color variations of black and gray. Some are countershaded: a type of protective coloration in which the dorsal (top) surface is darker than the ventral (underneath) surface. When lighting is from above, the animal appears inconspicuous.
What makes baleen whales unique?
baleen whale, (suborder Mysticeti), also called toothless whale, any cetacean possessing unique epidermal modifications of the mouth called baleen, which is used to filter food from water.
What are 2 characteristics that distinguish baleen whales?
The presence of baleen plates and teeth in the mouths mainly distinguish the two groups, and they are so named. Baleen whales are larger than toothed whales.
What is the texture of baleen?
Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails, skin and hair. Baleen is a skin derivative. Some whales, such as the bowhead whale, have longer baleen than others.
What are the characteristics of whales?
They are mammals, and they share the defining traits of that group: they breathe air, are warm-blooded, give live birth, suckle their young on milk, and have hair. All are entirely aquatic, with specialized adaptations such as flippers and tail flukes for living in water.
What is the function of baleen?
All baleen whales have baleen instead of teeth which they use to collect shrimp-like krill, plankton and small fish from the sea. These bristly baleen plates filter, sift, sieve or trap the whales’ favourite prey from seawater inside their mouths.
What does baleen feel like?
The (outside) non-fringed part of the baleen feels similar to a person’s fingernail. Inside the whale’s mouth, the plates are frayed. The frayed edges (inside the mouth) look and feel like stiff, thick plastic hair or long bristles from a scrub brush.
Is baleen soft?
Baleen is the soft, hair-like structure on the upper mouth of whales, such as the humpback whale in this photo, which allows them to trap prey in their mouth.
What are four characteristics used to classify whales?
Identifying whales at sea
- body length.
- presence of a dorsal fin.
- size and position of the dorsal fin.
- shape and size of flippers.
- shape of the head and general body shape.
- presence of a beak.
- shape of the blow.
- body colour and patterns.
What whales look like?
Blue whales look true blue underwater, but on the surface their coloring is more a mottled blue-gray. Their underbellies take on a yellowish hue from the millions of microorganisms that take up residence in their skin. The blue whale has a broad, flat head and a long, tapered body that ends in wide, triangular flukes.
How do baleen whales feed?
Baleen whales feed by filtering or straining food from the water. They love to eat krill, fish, zooplankton, phytoplankton, and algae. Some, such as the right whale, are called “skimmers”. These whales swim slowly with their huge mouths open to take in large amounts of water and food.
How do baleen whales move?
Most baleen whales are highly migratory, moving toward high-latitude (polar) feeding areas in the summer and toward low-latitude (tropical) calving areas in the winter. Variations in water temperature, food availability, and feeding habits may account for movements of some animals.
Is baleen sharp?
“These results are the first to show that ancient baleen whales had extremely sharp teeth with one function—cutting the flesh of their prey,” Museums Victoria’s senior curator of vertebrate palaeontology Erich Fitzgerald said.
What is baleen made of?
Strong but flexible, baleen is made of the same substance as your fingernails – keratin. Discover more about this species in A Tale of A Whale, a photo essay about a whale named Phoenix.

How much teeth do baleen whales have?
Whales possess a varying number of teeth, depending on the individual species. Some kinds of whales only have one or two teeth, while others might have 240 teeth or even more. Dental patterns can vary. Some toothed whales have teeth in both their upper and lower jaws. Other whales only have teeth in their lower jaws.
How many blow holes does a baleen whale have?
Their nostrils, or blowholes, are situated at the top of the cranium. Baleen whales have two blowholes, as opposed to toothed whales which have one. These paired blowholes are longitudinal slits that converge anteriorly and widen posteriorly, which causes a V-shaped blow.
