Subfamily Caprinae is part of the ruminant family Bovidae, consisting of mostly medium-sized bovids. Its members are commonly referred to as goat-antelopes or caprids. 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 tribe Caprini (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.
