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.
What else can I help you with?

Do blue whales breath under water?
Mammals don't breathe under water. They hold their breath like you or I would...except their lungs are gigantic and they can hold their breath for hours. No they don't. Whales are mammals and thus need to breathe like most mammals do. In order to breathe, whales have blow holes on their heads. They come up to the surface of the water, bring their blow hole out of the water, open it and take in air, and then go back under water again. No basically.
