Common bottlenose dolphins are widespread, except in polar waters. They are extremely sociable and sometimes hunt their prey in teams. Being mammals, dolphins have to return to the surface to breathe every few minutes. They also need to sleep and can rest one side of their brain at a time allowing them to sleep whilst remaining conscious enough to surface and breathe. Common bottlenose dolphins have been known to help one another: injured dolphins are supported at the surface and protected by others within their group.

Bottlenose dolphins sleep with one side of their brain at a time so they can still swim to the surface to breathe.
