Zebra It is an inhabitant of the semi-arid grasslands of Ethiopia and northern Kenya. Grévy's zebra is the rarest species, and is classified as endangered. Although zebra species may have overlapping ranges, they do not interbreed. In captivity, plains zebras have been crossed with mountain zebras. The hybrid foals lacked a dewlap and resembled the plains zebra apart from their larger ears and their hindquarters pattern. Attempts to breed a Grévy's zebra stallion to mountain zebra mares resulted in a high rate of miscarriage. In captivity, crosses between zebras and other (non-zebra) equines have produced several distinct hybrids, including the zebroid,
Zebra zeedonk, zony, and zorse. In certain regions of Kenya, plains zebras and Grévy's zebra coexist, and fertile hybrids occur. The Hagerman horse ("Equus simplicidens") is sometimes referred to as the American zebra due to perceived similarities to the plains zebra, and sometimes depicted as striped. However, consensus appears to be that it wasn't particularly closely related to either "Hippotigiris" nor "Dolichohippus", nor is there unambiguous evidence that it had stripes. The common plains zebra is about at the shoulder with a body ranging from long with a tail. It can weigh up to , males being slightly bigger than females.
