Full Answer

Because they breathe air rather than survive on oxygen from the water, dolphins are considered mammals and not fish. Unlike humans, dolphins are voluntary breathers, which means they must think about breathing rather than breathing subconsciously. Because of this, dolphins are never fully asleep like humans; instead, a dolphin shuts down only half of its brain while the other half remains awake to breathe.
