Zebra
There are three species of zebras: the plains zebra, the mountain zebra and the Grévy's zebra. The plains zebra and the mountain zebra belong to the subgenus Hippotigris, while Grévy's zebra is the sole species of subgenus Dolichohippus. The latter resembles an ass, to which zebras are closely related, while the former two look more horse-like. All three belong to the genus Equus, along with other living equids.
