The definitive characteristic of all mammals is that they feed their young on mothers' milk. No other animal group does this. Mammals are also unique in that their skin covering is fur, hair or plain skin.
With the exception of the platypus and the two species of echidna (which belong to a subgroup of mammals known as monotremes), their young are born alive. However, this trait is common among many fish, reptiles and a small number of amphibians.
