Species of antelope (Antidorcas marsupialis), native to treeless plains of southern Africa, the national emblem of South Africa. It stands about 30 in. (80 cm) high at the shoulder, and both sexes have ringed, lyre-shaped horns. A fold of skin from midback to rump can be opened to display a crest of white hair. The reddish brown upper body has a broad horizontal dark-brown band on each side; the underparts, head, tail, and rump are white. When excited, the springbok, with head down, hooves bunched, and back arched, makes a series of stiff-legged, vertical leaps up to 12 ft (3.5 m) high, an action called pronking.
