There are three species of Zebra -- all are black (or dark brown) and white striped small horses but the basic stripe pattern and some other features vary.
All are native to Africa.
Grevy's Zebra, also called the Imperial Zebra, from East Africa is related to the ass/donkey rather than to the horse like the Mountain and Plains Zebras.
Despite that, it is the largest zebra at some 5 feet to the shoulder and even the tallest wild equid, taller than the Asian Wild Ass/Khulan and Przewalski's
It has much narrower stripes than the other two Zebra species, has a white belly and longer ears.
Where its range coincides with the Plains Zebras they can be found in the same herds but only rarely produce hybrids with the Plains species in the wild.
Grevy's Zebra mother with foal. Foals start with brown and white stripes, the brown gradually turning black as they mature.
