How do dolphines breathe?

Answer 1

Dolphins breathe by using their blow holes and blowing air constantly so they can actually breathe.

Dolphins breathe through a hole on the top of their heads called a blowhole. The blowhole acts like a nose. Just before they reach the surface, they blow all the air from the blowhole. When they reach the surface, they inhale air through the blowhole in less than a second! A flap quickly closes the blowhole, trapping the air, and the dolphins dive back into the water.
They are mammals and breathe with lungs, just like all mammals do.
A Dolfin breathes by lungs but on top of its head it has a blow hole ad there push or suck up air when there under the water
Dolphins breath by surfacing every so often to get air...dolphins can stay up to 15 minutes under the surface of the ocean, without having to re-surface.
they breath form their air hole
