My favourite animal is a dolphin.
I think they're playful and friendly.
They rescue people and help other ill dolphins.

They are the cleverest of animals.
Their behavior shows that they have high mental abilities.
These animals can be about three meters long
and weigh 300 kilograms.
They also have 200 teeth. 
Dolphins have a gray-blue back and light stomach.
They have the high fin on the back
and wide fins on the sides.
 
Dolphins live in the World's Ocean, 
in seas like the Black and the Carribbean.
They can live about 30 years.

They gather in packs for hunting. 
Dolphins eat fish, shrimps and squids.
They use the echolocation for finding prey in the muddy water. 
They can swim with a speed of 30 kilometers an hour.
