The springbok (pronounced /ˈspriŋ-ˌbäk/) (Antidorcas marsupialis) is a medium-sized antelope found mainly in southern and southwestern Africa. The sole member of the genus Antidorcas, this bovid was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1780. Three subspecies are identified. A slender, long-legged antelope, the springbok reaches 71 to 86 cm (28 to 34 in) at the shoulder and weighs between 27 and 42 kg (60 and 93 lb). Both sexes have a pair of black, 35-to-50-centimetre (14 to 20 in) long horns that curve backward. The springbok is characterised by a white face, a dark stripe running from the eyes to the mouth, a light brown coat marked by a reddish brown stripe that runs from the upper foreleg to the buttocks across the flanks, and a white rump flap.
