Rorqual, gray, and pygmy right whales have grooves under the throat that extend to at least the pectoral flippers. Prey must occur in sufficient numbers to trigger the whale's interest, be within a certain size range so that the baleen plates can filter it, and be slow enough so that it cannot escape.
Rising Tide 2003), which allows us to model the disease in humans by using rodents and other mammals. Fin Whale (Balaenoptera physalus) The fin whale is the second-largest animal in the world, with a …
For species like the North Atlantic right whale, which migrates through some of the world's busiest shipping lanes, the biggest threat is from being struck by ships. While doing this, baleen whales use their tail fluke to propel themselves forward through vertical motion while using their flippers for steering, much like an otter.
Baleen whales generally then migrate to calving grounds in tropical waters during the winter months when plankton populations are low.
Baleen whales range in size from the 6 m (20 ft) and 3,000 kg (6,600 lb) pygmy right whale to the 31 m (102 ft) and 190 t (210 short tons) Although baleen whales are widespread, most species prefer the colder waters of the The meat, blubber, baleen, and oil of baleen whales have traditionally been used by the Cetotheriidae consists of only one living member: the pygmy right whale (Eschrichtiidae consists of only one living member: the gray whale (Mysticetes are also known as baleen whales because of the presence of baleen.

Lunge-feeding is where a whale rams a The first toothless ancestors of baleen whales appeared before the first radiation in the late Oligocene.The increase in size is likely due to shifts in climate that have resulted in seasonally shifting accumulations of plankton in various parts of the world, necessitating more efficiency traveling over long distances between widely distributed prey sources which also resulted in a lower metabolic rate, and feeding on baitballs.When swimming, baleen whales rely on their flippers for locomotion in a wing-like manner similar to penguins and Rorquals, needing to build speed to feed, have several adaptions for reducing Baleen whales have two flippers on the front, near the head. The horizontal lobes of the tail of a whale are called flukes (each lobe is called a fluke.
