The Sharpe's grysbok (Raphicerus sharpei) is a tiny, shy, reddish-brown antelope with white-streaked fur, giving it a grizzled look, featuring off-white markings around the eyes, muzzle and throat and short, stubby horns on males, known for its solitary, nocturnal habits in thick bush, preferring hiding to fleeing, and identified by its smooth, low run unlike zig-zagging duikers.
