Mammals

Mammals are warm-blooded vertebrates which, with the exception of a few notable species, nurse their young on milk produced by the female’s mammary glands, give birth to live young, and have bodies insulated by hair. Around one in four of the world’s mammals are currently threatened with extinction.
