The subfamily Caprinae, also sometimes referred to as the tribe Caprini, is part of the ruminant family Bovidae, and consists of mostly medium-sized . A member of this subfamily is called a caprine.
Prominent members include Ovis and goats, with some other members referred to as goat antelopes. Some earlier taxonomies considered Caprinae a separate family called Capridae (with the members being caprids), but now it is usually considered either a subfamily within the Bovidae, or a tribe within the subfamily Antilopinae of the family Bovidae, with caprines being a type of bovid.
Many species have become extinct since the last ice age, probably largely because of human interaction. Of the survivors:
Members of the group vary considerably in size, from just over long for a full-grown Nemorhaedus ( Nemorhaedus goral), to almost long for a musk ox, and from under to more than . Musk oxen in captivity have reached over .
The lifestyles of caprids fall into two broad classes: 'resource-defenders', which are territorial and defend a small, food-rich area against other members of the same species; and 'grazers', which gather together into herds and roam freely over a larger, usually relatively infertile area.
The resource-defenders are the more primitive group: they tend to be smaller, dark in colour, males and females fairly alike, have long, tessellated ears, long manes, and dagger-shaped horns. The grazers (sometimes collectively known as tsoan caprids, from the Hebrew meaning sheep and goats) evolved more recently. They tend to be larger, highly social, and rather than mark territory with scent glands, they have highly evolved dominance behaviours. No sharp line divides the groups, but a continuum varies from the serows at one end of the spectrum to sheep, true goats, and musk oxen at the other.
The ancestors of the modern sheep and goats (both rather vague and ill-defined terms) are thought to have moved into mountainous regions – sheep becoming specialised occupants of the foothills and nearby plains, and relying on flight and flocking for defence against predators, and goats adapting to very steep terrain where predators are at a disadvantage.
