The dolphins and their feature.

The dolphin is a marine mammal that is near the coast. There are 32 species, the best known is the bottlenose dolphin that is what we can see in zoos and water parks. Its size can vary according to the species it belongs and can vary from 3 meters up to 1.2 meters long.

Dolphins communicate using a noise, the other dolphins interpret the echoes generated in contact with the objects around you and using dance movements, doing stunts and jumps.
Dolphins prefer warm waters and often they swim with large flocks . They eat a variety of fish. Each dolphin has markings that identify and distinguish it from the others.

One of the things that are strangest is the language of dolphins because  thanks to her offspring can suck mother's milk without mixing with seawater. When they sleep, they are always alert; can close one eye and the other half is open, so although it is still sleeping they even watching what you swim.

The reproduction is similar to that of humans. The male follows the female and if he happens to copulate  she accept. Usually the mating season is all year, except those living in colder waters.
