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.
The whale uses its snout to forage by dislodging tiny creatures from the seafloor. It then filters these morsels with its baleenâa comblike strainer of plates in the upper jaw. A piece of gray whale baleen, also called whalebone, is about 18 inches (46 centimeters) long and has a consistency much like a fingernail.
