The gemsbok or gemsbuck is a large African antelope, of the Oryx genus. Gemsbok live in herds of about 10-40 animals, which consist of a dominant male, a few non-dominant males, and females. The female's horns may be curved but the male's are thicker and parallel. Male gemsbok have been known to gore attacking lions with their horns. There are two types of gemsbok: a northern and southern variety. The northern gemsboks have black-fringed ears while the southern ones have longer horns and more rounded ears.
Gemsbok are mainly desert-dwelling and do not depend on drinking to supply their physiological water needs.
