Despite living in the water, whales breathe air. And like humans, they are warm-blooded mammals who nurse their young. A thick layer of fat called blubber insulates them from cold ocean waters. Some whales are known as baleen whales including blue, right, bowhead, sei and gray whales. This refers to the fact that they have special bristle-like structures in their mouths (called baleen) that strains food from the water.
Baleen is a filter-feeder system inside the mouths of baleen whales. The baleen system works when a whale opens its mouth underwater and the whale takes in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as food source for the whale.Baleen is similar to bristles and is made of keratin, the same substance found in human fingernails and hair. Some whales, such as the bowhead whale, have longer baleen than others.Other whales, such as the gray whale, only use one side of their baleen.he whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as food source for the whale.
