Grevy's zebra weighs 350 - 450 kg (770 - 990 lb). It lives in arid, open bushed grassland and is adapted to survive droughts, as long as it can reach water every several days. Grasses make up about 70% of the Grevy's zebra's diet. It also browses on shrubs and trees. The Grevy's zebra has an open society in which females with their young and males on established territories are the focal points. There are no permanent bonds between adults. They are solitary or live in a variety of different associations that usually do not last longer than a few months. Some stallions are territorial, with territories of up to 12 sq km (4.6 sq mi). The resident stallion tolerates other stallions in his territory, but they do not interfere with the resident stallion when he is mating. 

The Grevy's zebra formerly occurred from central Ethiopia to Somalia and northern Kenya. It experienced a significant decline in the 1970's, apparently due to poaching to obtain the zebra's attractive hide for fashion. It is now found only in northeastern Ethiopia and some reserves in Kenya. 

Poaching of Grevy's zebra is no longer a threat, due to protection under CITES. Loss of grazing habitat and access to water, due to competition with increasing herds of domestic livestock, is the primary threat to the Grevy
