An interesting animal!

Hi! Today I am going to write about an animal that I find interesting, it’s the dolphin.

Dolphins are found almost every ocean in the world and in some important rivers. They prefer temperate zones and avoid very cold waters. Their habitat varies according to the species of the dolphin, there are more than 30! And it also varies according the access to food.

I think that the dolphins are very interesting; they are one of the most intelligent animals. The dolphins communicate with each other through different sounds, it is even said that they call each other by names, I think that is fascinating!

The dolphins are marine mammals and they stay with their mothers for 3 or even 8 years, that is a long time. Another interesting fact about dolphins is that when they are asleep, one part of their brain remains alert and awake to keeps them safe from predators and to breathe while they are asleep.

The dolphins usually have around 250 conical and sharp teeth, but the number of teeth changes according to the age of the dolphin. Dolphin teeth grow larger by producing growth layers in the root, counting these layers is the easiest way to know the age of a dolphin.
