Well, the whale takes turns of its brain sleeping. As whales have to be awake to breathe, the whale rests 1 side of the brain to make sure its breathing, alert of any dangers etc, while one side remains asleep.

How are pink dolphins and dolphins different by how they sleep?
They're not different. All dolphins (and whales for that matter) have half their brain sleeping and half their brain awake at all times. This is so they can go to the surface to breath and are not caught off guard by predators.

Why is half of my brain feel asleep?
Not necessarily. The brain is constantly working regardless of whether you're awake or asleep. Some areas, however, will be more active when sleep and some when you're awake.

They don't drown because some whales go up to shore and sleep up there so then they don't drowned.
Do aardvarks sleep?
Of course, every animal sleeps but some animals (in particular marine mammals) such as dolphins sleep keeping half their brain awake, to keep alert of predators.
If whales are mammals how come they can sleep under water and we can't?
Science isn't entirely clear on this. One option is that they're simply able to hold their breath long enough to get a useful nap between breaths. Another is that they somehow sleep with one half of the brain at a time, leaving the other half awake to sort out basic functions like breathing without drowning.
Do humpback whales sleep?
Yes, whales and dolphins do sleep; however, they do not sleep in the same way that humans do. For example, while human sleep involves a period of unconsciousness followed by a period of conscious dreaming or REM sleep, cetaceans (whales and dolphins) show a pattern of unihemispheric slow-wave sleep, meaning that they only sleep with one half of their brain at a time. This allows them to remain aware of their surroundings and continue to surface for air, even while sleeping.
Do horses sleep with one eye open?
Giraffes don't sleep with one eye open. There's no point in keeping an eye open unless there's a brain awake to interpret what the eye is seeing. And the only animals considered to be able to sleep with half the brain at a time are whales and Dolphins.
How do whales sleep under water?
Dolphin's actually have a unique way of sleeping; they sleep with one half of their brain at a time while the other have controls their swimming and breathing. Once one half of the brain gets the amount of sleep it needs, it switches and the other half of the brain sleeps while the newly rested half takes over control of breathing and swimming. Very interesting stuff that I learned in Biopsychology recently.
