The addax is a sandy to almost white color during the summer, darkening to a grayish brown in the winter. White markings are present on the face, ears, belly, hips, and legs, and there is a black tuft of hair on the forehead. Horns are present on both males and females, average about 72 cm in length.

Due to its slow movements, the antelope is an easy target for its predators: lions, humans, African wild dogs, cheetahs, and leopards. Breeding season is at its peak during winter and early spring. The natural habitat of the addax are arid regions, semideserts and sandy and stony deserts.

The addax eat only certain parts of the plant and tend to crop the Aristida grasses neatly to the same height. By contrast, whenfeeding on Panicum grass, the drier outer leaves are left alone while they eat the tender, inner shoots and seeds.

Addax nasomaculatus.

Addax antelopes are also called screwhorn antelopes because of their long, twisted horns. Addaxes are critically endangered animals because there are so few of them left in the wild; however, there are many in zoos and wildlife parks.
