The family Balaenidae, the right whales, contains two genera and four species. All right whales have no ventral grooves; a distinctive head shape with a strongly arched, narrow rostrum, bowed lower jaw; lower lips that enfold the sides and front of the rostrum; and long, narrow, elastic baleen plates (up to nine times longer than wide) with fine baleen fringes.
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
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.
Although the whales no longer face pressure from commercial whaling, humans remain by far the greatest threat to these species: the two leading causes of death are being struck by ships and entanglement in fishing gear. Today, the North Atlantic and North Pacific right whales are among the most endangered whales in the world.
Balaenidae (/ b ə ˈ l ɛ n ɪ d eɪ,-d iː /) is a family of whales of the parvorder Mysticeti (baleen whales) that contains mostly fossil taxa and two living genera: the right whale (genus Eubalaena), and the closely related bowhead whale (genus Balaena).
The blue whale is a type of baleen whale that, depending on the time of year, is found in oceans worldwide. Its scientific name is Balaenoptera musculus . Translated, Balaenoptera means “winged ...
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]
