Gemsbok
The gemsbok or gemsbuck (Oryx gazella) is a large antelope in the Oryx genus. It is native to the arid regions (for example the Kalahari Desert) of southern Africa, but formerly some authorities included the East African Oryx as a subspecies. Its current population in South Africa is 373,000.
Gemsbok are light brownish-grey to tan in colour, with lighter patches to the bottom rear of the rump. Their tails are long and black in colour. A blackish stripe extends from the chin down the bottom edge of the neck through the join 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 blackish on the legs (none on the hindlegs), and less blackish on the lower flanks.
Gemsbok are about 1.2 metres (3 ft 11 in) at the shoulder, and males can weigh between 220–250 kilograms (490–550 lb) while females weigh 180–210 kilograms (400–460 lb).
