Zebras, who are natives of Africa, belong to the family of horses and donkeys. There are three different species of zebras - Plains Zebra, Grevy's Zebra and Mountain Zebra. The zebras live in a wide range of habitats like mountains, hills, woodlands, grasslands and Savannahs. Plain Zebras are found in the grasslands of southern and east Africa, Mountain Zebras can be seen in southwest Africa and Grevy's Zebra dwells in Ethiopia and Kenya. While Plains Zebras are plenty in number, Grevy's Zebra and Mountain Zebra are considered as endangered species. Source

The Plains zebras are social animals. Although they may live alone, they usually form bachelor groups and small families of 5-20 animals, consisting of a dominant male, mares and offspring. The stripes help them confuse predators by making it hard for them to single out any one of them while in motion.Source
If a predator stalks the zebra herd, the zebras form a semi-circle and watch the predator. If the predator decides to attack, the zebras can bite and kick in order to defend themselves. Herd stallions defend their groups by running in the rear as they flee, kicking and biting attackers. When one zebra is wounded by a predator, the rest of the herd forms a circle around the injured animal in order to protect it from further harm. Source
