Gemsbok's natural range. |
The gemsbok or gemsbuck (Oryx gazella) is a large antelope in the Oryx genus. 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 is depicted on the coat of arms of Namibia, where the current population of the species is estimated at 373,000 individuals.
The name "gemsbok" in English is derived from Afrikaans gemsbok, which itself is derived from the Dutch name of the male chamois, gemsbok. Although some superficial similarities in appearance (especially in the facial pattern) are noticed, the chamois and the oryx are not closely related. The usual pronunciation in English is /ˈɡɛmzbɒk/.
Gemsbok are light brownish-grey to tan in colour, with lighter patches toward the bottom rear of the rump. Their tails are long and black in colour. A blackish stripe extends from the chin down the lower edge of the neck, through the juncture of the shoulder and leg along the lower flank of each side to the blackish section of the rear leg. They have muscular necks and shoulders, and their legs have white 'socks' with a black patch on the front of both the front legs, and both genders have long, straight horns. Comparably, the East African oryx lacks a dark patch at the base of the tail, has less black on the legs (none on the hindlegs), and less black on the lower flanks. One very rare condition is the "Golden Oryx", in which the Gemsboks black markings are muted and now appear golden.
Gemsbok are the largest species in the Oryx genus. 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).
