Yes they do. At night, they shut off half there brains which allows them to be alert of enemy's and not drown when sleeping. One side of their brains sleeps while the other concentrates on staying alive and natural functions such as breathing. Once that side was asleep is refreshed it swaps round, so the other side gets a chance of rest and respite.
