Herd Animals

Zebras are herd animals, like goats, sheep, and cattle. They live, eat, and travel in groups. Staying with the herd provides protection for the zebras. It is harder for a predator to catch one zebra when it is in a large group of other zebras. Having many zebras in the herd also means that there are many eyes keeping watch for predators, such as lions, leopards, hyenas, and cheetahs. 

Sometimes a herd will join another "super herd," and thousands of zebras may travel together in search of new places to graze. Zebra herds may also pick up other animals as they travel, like wildebeest and antelope.
