Fish are cold-blooded, have scales over their skin, have laterally flattened bodied, are finned, require immersion in water to survive, and reproduce by laying eggs.

Mammals are warm-blooded,have hair over their skin, are mostly four-limbed in the body forms, breath air but some live in water, and reproduce by carrying their young inside the female body until they are born alive.

Most mammals care for their young, while most fish do not.
