Dolphins are marine mammals. There αre almost forty species of dolphins. Dolphins live in all oceans of the planet and even in some important rivers. Τhey vary in size; they can be from 1.2 metres and forty kilos up to 9.5 metres and 10 tones. They can jump very high outside the water. They can jump over 4.9 metres. They live forty- five to fifty years in the wild. Dolphins have blue or grey colour and black eyes.
Dolphins are among the most intelligent and friendly animals. They are very clever, charismatic, acrobatic animals and they like playing many games, too. Also their mouths are like a friendly smile.
Dolphins stay in groups for their entire life. They eat mostly fish, squids and shrimps. They track their prey through echolocation. They can know the location, the size and the shape of their target.
Dolphins sometimes follow fishing boats. People hunt them for their meat and their oil. Dolphins are usually trapped badly in fishing nets.
They are surely amazing animals!
