Dolphins are mammals. Most live in oceans, where water is

salty. But some live in rivers – there are oceanic dolphins and

river dolphins. Dolphins are usually from 1.5 metres to 4 metres

long. Dolphins breathe air. A dolphin's nose is on top of its head

so the dolphin can easily breathe on the surface of the water.

The skin of a dolphin is soft and smooth. Dolphins do not sleep

in a normal way. They have two sides of their brain, which they

use to sleep. One side sleeps, while the other side does not

sleep. They keep one eye open to watch for enemies while they

sleep. Dolphins also swim in circles when they are sleeping with

one of the eyes open to watch out for danger.

Dolphins are the friendliest animals in the sea and there are

a lot of stories about dolphins which help sailors. Dolphins are

clever animals. They look after other dolphins when they are ill,

care for very young dolphins and protect the weakest dolphins.

Some scientists think that dolphins have a language, other

scientists believe that dolphins communicate with each other

without words.
