Mammals are warm blooded, bear live young, nurse their young, and have hair (of some sort ) at least at some time in their lives. Penguins are animals, BUT not mammals. They are birds, although they swim rather than fly. Birds have feathers (although the penguins' are furry-like in feel) and lay eggs. Like mammals, birds have a backbone and are warm-blooded. Some mammals do lay eggs, like the Platypus, or the spiny echidna. But most bear live young.
