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.

Why dolphins and whales do not have gills?
Dolphins and whales are mammals, not fish, so they do not have gills. They breathe air through blowholes on the top of their heads, just like humans breathe through their noses. This allows them to dive deep into the ocean and still come up to the surface to breathe.
How can dolphins be whales but whales cant be dolphins?
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
