Hawaii Whale Research Foundation Since they are mammals and not fish, whales breathe air, are warm-blooded, give live birth, suckle their young, and yes, even have hair.
Whales breathe through blowholes, which are located on top of their heads.
Many species travel in pods or herds and communicate with one another through sounds, sight, touch, and taste. Collectively, whales are known as cetaceans. Some researchers believe that these whales can even kill or stun their prey with echolocating sounds. Their main diet consists of squid and fish. Some species, such as the killer whale and false killer whale, even consume seals, sea lions, and other cetaceans.
