They do not breathe underwater. They hold their breath under the water and surface to breathe.
Well, they don't, no whale can breath under water. For they are they only water mammal. They have blow holes on the top of them. Once down for a period of time, they will re-surface and breath.

A dolphin is a mammal and not a fish.
Yes, while he can live under water, he does need to surface to breath.
Dolphins and Whales can stay under water for so long is because they have blowholes to come to the surface and get air. They can stay under water for quite a while before they need another breath at the surface:) Need more help... Just ask!!!!!!!!!!!!!!
You'll either have to hold your breath or have a SCUBA tank.
Penguins DON'T breathe under water. Penguins breathe with lungs, and need to surface regularly to breathe. While diving, they simply hold their breath.
Dolphins can't breathe underwater because they are mammals. They go to the surface to breathe and then hold their breath while underwater
A human swimmer must use a snorkle to breath while swimming just below the water's surface. Aqualungs (air tanks) are used to breath under water, and allowing the swimmer to diver deeper. Goggles are used to help a swimmer to see under water.
Turtles do indeed breath oxygen. They are able to hold their breath for extended periods while either hiding or search for food under water.
A dolphin's blowhole helps it breath while it is in the water.
A Great Diving beetle will first collect air bubbles in their wings cases which allows them to breath while they are under water. The shape of their body and how they move their wings under water is what allows them to move quickly.
That is what happens when a whale breathes. They hold their breath when going under water, and when they surface they exhale to blow in seawater that has filled their blowhole while submerged.
