The gemsbok, gemsbuck or South African oryx (Oryx gazella) is a large antelope in the genus Oryx. It is native to the arid regions of Southern Africa, such as the Kalahari Desert.
Gemsbok are the largest species in the genus Oryx. They stand about 1.2 m (3.9 ft) at the shoulder. The body length can vary from 190 to 240 cm (75 to 94 in) and the tail measures 45 to 90 cm (18 to 35 in). Male gemsbok can weigh between 180 and 240 kg (400 and 530 lb), while females weigh 100–210 kg (220–460 lb).
Gemsbok are widely hunted for their spectacular horns that average 85 cm (33 in) in length. From a distance, the only outward difference between males and females is their horns, and many hunters mistake females for males each year. In males horns tend to be thicker with larger bases. Females have slightly longer, thinner horns. Female gemsbok use their horns to defend themselves and their offspring from predators, while males primarily use their horns to defend their territories from other males. Gemsbok are one of the few antelope species where female trophies are sometimes more desirable than male ones. A gemsbok horn can be fashioned into a natural trumpet and, according to some authorities, can be used as a shofar.
