The mountain zebra is the smallest species of zebra and also the earliest named zebra. Zebras are mammals of the genus Macroma in the order Quetziformes. They can be divided into three subspecies based on their body size and stripes, namely fine striped zebras, mountain zebras, and common zebras. Zebras are native to eastern, southern, and southwestern Africa, mainly inhabiting tropical and subtropical forests and grasslands. Zebras are social animals, usually living in groups of dozens or hundreds, and they go to ponds or streams to drink water in the morning and evening. Zebras are rare ornamental animals that people pursue for their skin and meat, and have been hunted in large numbers. Fine striped zebras are now on the brink of extinction.
