They don't drown because some whales go up to shore and sleep up there so then they don't drowned.
They wake up a little bit to surface and breathe, then sink and go back to sleep.
Some scientists suspect that whales put half of their brains to sleep at a time. That way whales are enough awake to keep from drowning all the time.
If they fully slept, they would drown. Half of their brains sleep at any one time.
Blue whales migrate. They cannot hibernate as they would drown. Whales sleep by switching off one side of the brain at a time.
Unlike most animals, whales are conscious breathers. All mammals sleep, but whales cannot afford to become unconscious for long because they may drown. It is thought that only one hemisphere of the whale's brain sleeps at a time, so they rest but are never completely asleep.
well if baby whales drowned when they were born i dont think there would be any adult whales. and there are, so, im gonna say no.
whales.... learned from TV its true wrong whales do sleep they do this in two basic methods of sleeping: they either rest quietly in the water, vertically or horizontally, or sleep while swimming slowly next to another animal
They dont have one, they live under water, but i dont know where they sleep as they are mammals and have to breach every few hours for air.
It is possible for a whale to drown. Whales are mammals and do not have gills, they must go to the surface to breath.
Yes. Sperm whales sleep vertically with head down.
they swim when they sleep
