What are dolphins? We all know that dolphins are small whales. Like other cetaceans, dolphins breathe not gills, but air. They never leave the sea, their cubs are born here. Mother feeds them with milk, so dolphins are mammals. They are warm-blooded. They have sharp teeth and their head ends with a bird-like mouth. The main food for dolphins is fish, shellfish and small marine animals. Ordinary dolphins are about 1.6 meters long. They have a big mouth with 80-100 teeth. The top is black or gray, and their belly is white with black fins. To the same family as dolphins are porpoises. The porpoise, living in all latitudes from Greenland to North Africa, is one of the most peaceful dolphins. In addition to fish, she eats crustaceans and even algae. Therefore, she tries to stay in shallow water, where there is a lot of food for her.
