Difference between whale and fish?

Question

Difference between whale and fish?

Answer 1

Whales are mammals and breath air which means they have lungs. Whales are normally bigger than fish and live in salt water. Fish have gills which means they don't have lungs and they can live in fresh or salt water. Some fish lay eggs, but all whales give live birth and their young drink milk from their mammary glands.

Answer 2

A whale is a mammal; it has lungs. Fish do not have lungs; they have gills.

Answer 3

A whale is a mammal, mainly because it nurses its young.  Also because it has hair, lungs, and vestigal legs (modified flippers).  Fish lay eggs, have scales, gills, and true fins.

Answer 4

A whale is a mammal. It has sexual organs like any land living mammal; in the female, a v****a and a p***s in the male. It gives birth like a land animal, and suckles its young. Whales have s*x just like land animals.
