Whales, dolphins, and porpoises are in an order known as cetaceans. They are fascinating to many people, possibly because of their size, their playful-seeming activities, or the attention to human threats to these animals. Like humans, these creatures of the sea breathe air, are warmblooded, and bear live young (called calves) which are nursed by their mothers.
