The springbok (Antidorcas marsupialis) is a medium-sized brown and white antelope of southwestern Africa. It was first described by the German zoologist, Eberhard August Wilhelm von Zimmermann in 1780. Three subspecies have been identified. The springbok is a slender antelope with long legs and neck, and with horns present in both sexes. Males are about 75 cm (30 in) tall at the shoulder, and females nearly 72 cm (28 in). They weigh between 33 and 48 kg (73 and 106 lb) for the males and 30 and 44 kg (66 and 97 lb) for the females. The springbok has a white head and face with dark stripes extending from a corner of the eyes to the corners of the mouth.
