The gemsbok, gemsbuck or South African oryx is a large antelope in the genus Oryx.
It is native to the arid regions of Southern Africa, such as the Kalahari Desert.
Some authorities formerly included the East African oryx as a subspecies.
The gemsbok (Oryx/Gazelle) is the largest; it stands up to 138 cm (54 inches) tall and weighs 238 kg (524 pounds).
It also has the most striking coloration: gray-brown with contrasting black and white body and facial markings.
