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,
Plains zebra and not endangered, though some populations such as in Tanzania have declined sharply. A dispute exists among biologists as to how to properly classify the various species of zebras. The plains zebra and mountain zebra are thought to belong to the subgenus "Hippotigris" and that Grévy's zebra is the sole species of subgenus "Dolichohippus". This is on account of Grévy's zebra resembling an ass (subgenus "Asinus"), while the plains zebra and mountain zebra are more horse-like. All three animals belong to the genus "Equus" along with other living equids. However, recent phylogenetic evidence finds that plains zebras are more closely
