Dolphin is the name of a group of sea animals closely realated to whales an porpoises. Like whales and porpoises, dolphins are mammals, not fish. Mammals, unlike fish, feed their young with milk that is produced in the mother's body. Also unlike the fish, dolphins have lungs and are warm blooded, that is, their body temperature always stays about the same, regardless of the temperature of their surroundings. Many scientists believe that the dolphins rank among the most intelligent animals, along with chimpanzees and dogs.
