Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. The fin whale is the fastest baleen whale, recorded swimming at 10 m/s (36 km/h; 22 mph). Baleen whales use their baleen plates to filter out food from the water by either lunge-feeding or skim-feeding
Baleen hair is attached to each baleen plate. Appearance of baleen hair in a whale's open mouth Cross-section of jaw showing bone a, gum b, rigid plate c and frayed baleen hairs d and e. Baleen is a filter-feeding system inside the mouths of baleen whales. To use baleen, the whale first opens its mouth underwater to take in water.
Diagram featuring the typical skeletal of a toothed whale (top) and a baleen whale (bottom) The cetacean skeleton is largely made up of cortical bone, which stabilizes the animal in the water. For this reason, the usual terrestrial compact bones, which are finely woven cancellous bone, are replaced with lighter and more elastic material.
National Geographic shared, "A piece of gray whale baleen, also called whalebone, is about 18 inches long and has a consistency much like a fingernail. Whalebone was once used to make ladies ...
Most baleen whales reside at the poles. To prevent the unborn baleen whale calves from dying of frostbite, the baleen mother must migrate to warmer calving/mating grounds. They will then stay there for a matter of months until the calf has developed enough blubber to survive the bitter temperatures of the poles.
The bowhead whale is the only baleen whale to spend its entire life in the Arctic and subarctic waters. [37] The Alaskan population spends the winter months in the southwestern Bering Sea. The group migrates northward in the spring, following openings in the ice, into the Chukchi and Beaufort seas. [38]
Articles relating to baleen whales (parvorder Mysticeti, whalebone whales), marine mammals in the infraorder Cetacea (whales, dolphins and porpoises), which use keratinaceous baleen plates (or "whalebone") in their mouths to sieve planktonic creatures from the water.
Baleen whales - a group that includes the blue whale, the largest animal in Earth's history - use a larynx, or voice box, anatomically modified to enable underwater vocalization, researchers said ...
