Equus grevyi (Grevy's zebra)

Synonyms: Equus faurei; Equus grevyi berberensis

Wikipedia Abstract

The Grévy's zebra (Equus grevyi), also known as the imperial zebra, is the largest extant wild equid and the largest and most threatened of the three species of zebra, the other two being the plains zebra and the mountain zebra. Named after Jules Grévy, it is the sole extant member of the subgenus Dolichohippus. The Grévy's zebra is found in Kenya and Ethiopia. Compared with other zebras, it is tall, has large ears, and its stripes are narrower.

EDGE Analysis

The largest of the living zebra species, Grévy’s zebra can be distinguished from the other zebras by its larger ears and narrower stripes. In recent history, the species has undergone one of the most substantial reductions of range of any African mammal. There has also been a 87 percent decline in numbers since the end of the 1970s. These declines were due in part to hunters killing the animals for their skins, which were made into fashionable clothing during the 1970s and 80s. While the species is no longer commercially hunted for its skin, numbers are continuing to decline due to competition with pastoral people and their domestic livestock, and to the long-term effects of overgrazing.
