A whale is a mammal because, unlike a fish, it meets certain criteria:
1 has lungs (fish take in oxygen via gills) so it comes to the surface to breathe
2 gives birth to live young (fish lay eggs)
3 feeds young from mammary glands (fish do not feed on milk)
4 is warmblooded (fish are cold-blooded)
5 possess a neo-cortex in the brain (fish do not)
6 has skin of 3 layers in thickness (fish have scales)
etc.
dolphin,porpoise, seals and sea lions are mammals too
