The Barbary sheep (Ammotragus lervia) is a species of caprid (goat-antelope) native to rocky mountains in North Africa. Six subspecies have been described. Although it is rare in its native North Africa, it has been introduced to North America, southern Europe, and elsewhere. It is also known as aoudad, waddan, arui, and arruis.
A goat-antelope, or caprid, is any of the species of mostly medium-sized bovids that make up the subfamily Caprinae (as treated here), part of the Bovidaefamily of ruminants. The domestic sheep and domestic goat are both part of the goat-antelope group by its widest definition, but some taxonomists prefer to use the term only for members of the Caprinae that are not members of the tribeCaprini (caprines). The term "goat-antelope" does not mean that these animals are true antelopes: a true antelope is a bovid with a cervid-like or antilocaprid-like morphology.
