As with horses, female zebras are called mares, and males are called stallions. All baby zebras are called foals, but young males are colts, and young females are fillies.
Zebras are social animals that travel in herds and graze together in grassy plains. Their herds usually consist of a stallion, several females and their offspring. These smaller units often combine to create large groups that can sometimes consist of thousands of zebras. These large numbers help them defend themselves against predators such as lions and hyenas. Each zebra's striped pattern is unique, and these patterns are often compared to a human's fingerprint in that no two are alike.
