How do whales breathe
Answers
Answer:
whales and dolphins are mammals and breathe air into their lungs, just like we do. ... they breathe through nostrils, called a blowhole, located right on top of their heads. this allows them to take breaths by exposing just the top of their heads to the air while they are swimming or resting under the water.

Answer:
They are mammals. People are mammals too. Mammals are the group of animals that breath air using lungs, give birth to live young (rather than laying eggs).
Whales come to the surface of the ocean. Sometimes they lie right at the surface of the water, with just a part of their back sticking out. Look closely at a picture of a whale or dolphin; can you see a nose on the whale? You can’t, because whales don’t have noses like you and me. Instead they have a hole – called a “blow hole” – on top of their heads. Sometimes when a whale breathes air out of its blow hole, it shows up as a spray or mist – called a “spout” – that can be seen many miles away. Blow holes are surrounded by muscles that keep the hole closed when the whale or dolphin is under water and open it when the animal is at the surface and needs to breathe.
