What Is a School of Whales Called?

Whales live in all the world's oceans. In spite of living exclusively in the water, whales are air-breathing creatures and are warm-blooded mammals. Whales have a thick layer of fat called blubber that serves as an insulator against the cold waters of the ocean. Some whales, such as blue whales, have a bristle-like structure that they use to strain the water for food. Other whales, such as sperm whales, have teeth.
