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.
A white rhino's horns are slightly smaller, and a Sumatran rhinos horns are about 10 to 31 inches (25 to 79 cm) for the front and less than 3 inches (7 cm) for the rear. The greater one-horned rhino's horn is 8 to 24 inches (20 to 61 cm), and Javan rhinos have a horn that is about 10 inches (25 cm) long.he word rhinoceros comes from the Greek rhino (nose) and ceros (horn). There are five species and 11 subspecies of rhino; some have two horns, while others have one.
