People also ask
Are whales mammals or fish?
I thought whales were mammals. The point of this thread is mammals are fish, so whales, being mammals, are fish. Do they still classify ectothermic fish as mammals?
What do whales do?
Whales are warm-blooded, breathe air, give birth to live young (they have a pregnancy/gestation period), and produce milk to feed their newborns.
Are whales the ancestors of fish?
The ancestors of fish are ancient fish, who also lived in the water rather than on land. While some ancient fish developed into land animals whose descendants returned to the water as whales, this makes whales only very distant relatives to fish.

Do whales nurse their young like fish?
Like other mammals, whales nurse their calves. Fish do not have mammary glands or nurse their young. And where fish have scales, whales have smooth skin. Whales have blubber, a layer of fat that helps to keep them warm, generating their own body heat as other mammals do.
