My favorite animal

My favorite animal is the dolphin. They are the one of the most intelligent animals in the animal kingdom, they have many features in common with humans like the communication with others dolphins by means of the echolocation, they are able to solve problems, they live in family groups and when other member of the family is wounded the others dolphins help him even if he needs breath.
They have a fusiform body adapted to swimming fast, the tail fin, called flow, is used for propulsion, while the pectoral fins are used for directional control of swimming. They possess in the head the melon, a spherical organ used for echolocation. Their brain is large with well developed cerebral cortex compared with the average of mammals
In their first months of life they are feed for breast milk because they are mammals and then they eat fish and squid. They live in all oceans except in the cold waters of the poles, they are relatively close of the coasts and often interact with humans.
I like this animals because they are very similar with us in many features and because they help the others members of their family. Maybe they are more intelligent than us and we have not even noticed.
