About zebras

Zebra, member of the horse family with an eye-catching coat of black and white stripes. Zebras are found only in Africa, but their remarkable markings make them among the most familiar mammals in the world. There are three species of zebras, each with a distinctive stripe pattern: Grévy’s zebra, the mountain zebra, and the plains zebra (also known as Burchell’s zebra).
Zebras are members of the family Equidae, which also includes horses and asses. The earliest known ancestor of the animals in this family was a small animal called Hyracotherium, or more commonly, Eohippus, which lived 60 million years ago during the Pleistocene Epoch. Animals known to be the direct ancestors of the modern horse, ass, and zebra appeared in Europe, Africa, and Asia about 4 million years ago during the Pliocene Epoch.
The water needs of each zebra species vary, and this factor helps to explain differences in where they live.
Grévy’s zebra is the best at coping with drought conditions. It lives in grasslands and thorny scrublands on the borders of northern Kenya, Somalia, and Ethiopia, a harsh region scorched by high temperatures. During the dry season when rivers, streams, and other surface waters often dry up, Grévy’s zebras survive by using their hooves to dig waterholes in riverbed sand.
The mountain zebra lives in the high ground of South Africa, and in the coastal hills of Namibia and Angola. Like Grévy’s zebra, it is also drought-adapted and will dig for water when supplies become scarce. However, the mountain zebra survives the dry season largely by migrating to higher ground, where moisture condenses in the cooler air to form rain or snow.
Compared to the Grévy’s zebra and the mountain zebra, the plains zebra has a much broader range. It lives throughout the grasslands, savanna, and scrub of East Africa, reaching as far...
