Addax

The Addax (Addax nasomaculatus), also known as the white antelope and the screwhorn antelope, is an antelope native to the Sahara Desert. The pale antelope, as implied by its alternate name, has long, twisted horns that range in length from 55 to 80 cm for females and 70 to 85 cm for males. At the shoulder, men stand between 105 and 115 cm and women between 95 and 110 cm. Because the females are smaller than the males, they exhibit sexual dimorphism. In the winter, the coat is greyish-brown with white hindquarters and legs, and long, brown hair covers the head, neck, and shoulders. In the summer, the coat turns almost entirely white or sandy blonde.

The addax mostly consumes grasses and the leaves of any nearby bushes, shrubs, and leguminous plants. They can survive for extended periods of time without water, which makes them well-adapted to dwell in their desert habitat. The Addax live in herds of five to twenty animals, both males, and females. The oldest female serves as their leader. The addax moves slowly, making it easy prey for people, lions, leopards, cheetahs, and African wild dogs. Winter and the first several weeks of spring are the busiest times for breeding. Arid areas, semideserts, and stony and sandy deserts are addax's native habitats.
