This document provides an overview of the class Mammalia. It notes that mammals are warm-blooded, have hair or fur, and give birth to live young which they feed milk. It divides mammals into three kinds: placental mammals, marsupials, and monotremes. It provides examples of orders within each kind and some interesting facts about the largest, smallest, tallest and fastest mammals.
