The Addax (Addax nasomaculatus) is a desert living antelope and is well adapted to its harsh habitat; the hooves are splayed to enable them to travel on sand, and these antelope produce highly concentrated urine as a method of conserving water. The short, glossy coat is a grey-brown colour in the winter, fading to almost white during the summer months. The underparts, rump, limbs, chin, lips and inside of the ears are white, as is the x-shaped blaze on the face. There is a tuft of dark hair on the forehead and the horns are long and twisted in both sexes.
