The steenbok is sometimes known as the steinbuck or steinbok. Steenbok resemble small Oribi, standing 45–60 cm (16″-24″) at the shoulder. Their pelage (coat) is any shade from fawn to rufous, typically rather orange. The underside, including chin and throat, is white, as is the ring around the eye. Ears are large with “finger-marks” on the inside. Males have straight, smooth, parallel horns 7–19 cm long (see image left). There is a black crescent-shape between the ears, a long black bridge to the glossy black nose, and a black circular scent-gland in front of the eye. The tail is not usually visible, being only 4–6 cm long.
Steenbok are active during the day and the night; however, during hotter periods, they rest under shade during the heat of the day. The time spent feeding at night increases in the dry season. While resting, they may be busy grooming, ruminating or taking brief spells of sleep.
At the first sign of trouble, steenbok typically lie low in the vegetation. If a predator or perceived threat comes closer, a steenbok will leap away and follow a zigzag route to try to shake off the pursuer. Escaping steenbok frequently stop to look back, and flight is alternated with prostration during extended pursuit. They are known to take refuge in the burrows of Aardvarks.
