They have black markings running from the horns over the white face down the cheeks, down the throat and front part of the neck, through the junction of the shoulder and leg along the lower flanks (forming a borderline between the white belly and greyish-brown upper body) all the way to the midsection of the rear legs. The lower parts of the legs are covered in white socks. Both sexes have long straight horns.

HABITS: Associated with open dry, dessert-like landscape. Their diet consists out of grass, wild melons and succulent bulbs.
