Whales and dolphins are mammals and must breathe air to survive. Furthermore, unlike humans and other mammals, they are 'voluntary breathers', which means they must physically remember to go to the surface and breathe!
Depending on the species of whale or dolphin, lung capacity differs. But, they all return to the surface of the water, open a blowhole on the top of their heads (a watertight valve) expel air and quickly take in new before going down below the water's surface.
Through their blowhole.
Both whales and dolphins are mammals, they do not breath underwater. Although, they do have a high lung capacity which allows them to stay under water for a long period of time.
Dolphins, whales, and porpoises breath through their blowholes at the top of their hands when they come up to the surface.
Whales and Dolphins Breathe through blowholes, modified nostrils on top of their heads.
Whales don't need to breathe through their mouths. Instead, they breathe through their blowholes on top of their heads, like the dolphins and porpoises.

They can't. Dolphins and Whales have lungs, not gills. they have to Surface to Breathe. They hold their breath while diving.
Yes, whales are mammals. As are dolphins and humans.
Yes they are. All whales and dolphins are. They breathe through lungs not gills, must come to the surface to breathe, has fuzz on their beak when they are a baby (it falls off) and has live birth.
Whales and dolphins are mammals. They both have at least one hair/fur on them and they breathe air (thats why the have blowholes).
They don't. Dolphins and whales breathe air just like we do. They can hold their breath for a long time, but they come up to the surface to breathe.
Whales Breathe through a blowhole, a modified nostril at the top of their head.
yes by their blowhole
A blowhole is what whales and dolphins use to breathe air.
They breathe through their blowhole.
Because dolphins has a blow-hole to sprout water and breathe like a whale while a whale is bigger in size and it can't do tricks like dolphin
