Mammals are a particular class of animal. What makes an animal a mammal are several things. First, they must have glands that give milk.This is to feed their babies. Second, they are warm-blooded. Third, all mammals have fur or hair. Humans are mammals and so are dogs, whales, elephants, and horses.he largest land mammal is the elephant followed by the rhino and the hippo (which does spend a lot of time in the water). The smallest mammal is the Kitty's hog-nosed bat. This bat is 1.2 inches long and weighs less than 1/2 a pound.
Rhinos and horses both belong to the order Perissodactyla, the odd-toed ungulates (hoofed mammals), whilst hippos and pigs belong to the order Artiodactyla, the even-toed ungulates. Source(s): I used to be a zookeeper and have studied animals all my life.
