they breathe, just like the rest of the mammals on this planet. they breathe through their blowhole, on the top of their head. they surface and the blowhole comes out of the water and they breathe, just like we do. some whales can hold their breath for up to an hour underwater. when you see that spurt of mist that comes from the top of the whales head, that's the whale breathing.

Humans enhale air and our lungs divide all other components and expell it except oxygen.
How does a whale hold its breath?
Whales don't breath underwater.They hold their breath underwater instead.Whales are mammals like us.They have lungs like us so they need to breath air above the water like we do. A whale can hold it's breath for up to half an hour underwater and thats only because it's lungs are huge.Our lungs only partly fill with air.A whale uses it's blowhole to breathe in air and when you see water spurting from a whale blowhole thats just the water vapour from the whale's lungs and any water around the blowhole.they need oxygen like us.If we didn't get oxygen we will die.
