And they live in a tribe!

Dolphins live in a tribe, just like the American Indians in days gone by.
Several families live together within it.
There can be up to 150 dolphins in each tribe.
It can take up an area of about 100 kilometres spread out along the coast  between the beaches and the high
seas.

Dolphins talk to one another using whistles and clicks.

The mother is the centre of the family.
She lives with her sisters, her daughters and all the baby dolphins as part of a little creche. There are also grandmother and grandfather dolphins.
The youngest members respect them and listen to them because the older ones know lots of things.

When they get bigger, the young male dolphins leave on their travels, although they return from time to time to say ‘hello’ to their
families. The daughters accompany them sometimes, but return very quickly to their mother, especially when they are going to have a baby.

The older dolphins do not swim very far away from the mothers’ territory and protect them if a shark
attacks.

Above is an example of the way Black Sea dolphins hunt.
It is called the ‘kettle technique’.

Everyone in the tribe has a name.
This is what is called the ‘whistle signature of the dolphin’. Every dolphin has to learn its name when it is young.

When two dolphins meet one another they exchange names.
In this way they know where the other one comes from and to which family it belongs.
The sounds they exchange are ultrasounds.
Dogs would be able to hear them but not us.

In the evening they all leave to hunt as a group.
They manage to gather the fish together into a ball shape by letting out piercing cries and by surrounding
them with bubbles. In this way it is very easy to catch them.

Every dolphin tribe speaks a different language.
Each one has its own way of life and preferred hunting methods.
