Grevy's zebras are not only the largest zebras, but also the largest living wild horses. They have large, rounded ears and very narrow stripes that form a whorl on the rump and extend to the hooves. The Grevy's zebra's black and white stripes are set extremely close together. Those stripes on the hindquarters remain vertical until above the hind legs (rather than being primarily horizontal as in other zebra species), at which point an interesting triangular interface is created. A wide black line passes down the spine, separated from the striping on the sides by white bands, while the white belly coloration extends part way up the sides. Fine horizontal striping extends all the way down the legs to the hooves. The head is large, with a grey to tan muzzle surrounded by a 'halo' of white. The ears are extremely large, with rounded tips, and wide black and white striping on their backs. A tall mane of erect hair on the nape of the neck is striped continuously with the body.
Restricted to East Africa (Wilson & Reeder, 1993), the Grevy’s zebras occupies arid areas in Ethiopia (to the north-east of Lake Turkana , in the Ogaden and Awash Valleys ) and Kenya (Churcher, 1993), while the species is likely to be completely exterminated in Somalia since the 1970s ( Duncan , 1992). Its distribution map was obtained by joining the two accurate maps in Duncan (1992) and Churcher (1993). It was then checked to match protected area boundaries

This species inhabits semi-arid shrublands and grasslands (Duncan, 1992; Churcher, 1993; Kingdon, 1997).
