Dolphins are such interesting creatures that people find it hard to believe that a dolphin is simply a whale! There is an order of aquatic mammals that scientists call “Cetacea”. To this order belong whales, dolphins, and porpoises. Dolphins are small whales that belong to the toothed-whale group. Porpoises are a kind of dolphin without beaks but with a triangular back fin and spade-shaped teeth.
The toothed whale lives on cuttlefish, squids, crabs, and many kinds of fish, which they chase and capture. The grampus, or killer whale, which is really a large dolphin, is the only cetacean that eats other warm-blooded animals. It is about 9 meters long and easily catches seals. The other dolphins are not often more than 3 meters long and their heads are quite small. Dolphins live in great herds and seem to enjoy the following ships. The common dolphin, which may be found in all temperate and tropical seas, has a tail shaped like a half-moon. The black of the back contrasts with the white belly.
Scientists are very interested in the way dolphins move through the water avoiding danger, and in the call notes, they use it in communicating with each other. It is believed that porpoises and dolphins are capable of making sounds that have more “meaning” than any other creature in the sea.
