"This antelope was first described by French zoologist and anatomist Henri Blainville in 1816. It is placed in the monotypic genus ""Addax"" and family Bovidae. Henri Blainville observed syntypes in Bullock's Pantherion and the Museum of the Royal College of Surgeons. English naturalist Richard Lydekker stated their type locality to be probably Senegambia, though he did not have anything to support the claim. Finally, from a discussion in 1898, it became more probable that British hunters or collectors obtained the addax from the part of Sahara in Tunisia. The generic name ""Addax"" is thought to be obtained from an Arabic"
"its slow movements, the addax is an easy target for predators such as lions, humans, African hunting dogs, cheetahs and leopards. Caracals, hyenas and servals attack calves. The addax are normally not aggressive, though individuals may charge if they are disturbed. The addax are amply suited to live in the deep desert under extreme conditions. They can survive without free water almost indefinitely, because they get moisture from their food and dew that condenses on plants. Scientists believe the addax has a special lining in its stomach that stores water in pouches to use in times of dehydration. They also"

Addax have always been infected with nematodes in the Trichostrongyloidea and Strongyloidea superfamilies. In an exotic ranch in Texas, an addax was found host to the nematodes ""Haemonchus contortus"" and ""Longistrongylus curvispiculum"" in its abomasum, of which the former was dominant. These animals are mainly nocturnal, particularly in summers. In the day, they dig into the sand in shady locations and rest in these depressions, which also protect them from sandstorms.

In the winter, it is greyish-brown with white hindquarters and legs, and long, brown hair on the head, neck, and shoulders. In the summer, the coat turns almost completely white or sandy blonde. Their head is marked with brown or black patches that form an 'X' over their noses. They have scraggly beards and prominent red nostrils. Long, black hairs stick out between their curved and spiralling horns, ending in a short mane on the neck."
"The horns, which are found on both males and females, have two to three twists and are typically in females and in males, although the maximum recorded length is . The lower and mid portions of the horns are marked with a series of 30 to 35 ring-shaped ridges. The tail is short and slender, ending in a puff of black hair. The hooves are broad with flat soles and strong dewclaws to help them walk on soft sand. All four feet possess scent glands. The life span of the addax is up to 19 years in the wild, which"

The addax have a strong social structure, probably based on age, and herds are led by the oldest female. Herds are more likely to be found along the northern edge of the tropical rain system during the summer and move north as winter falls.

Primarily grazers, their staple foods include ""Aristida"", ""Panicum"", and ""Stipagrostis"", and they will only consume browse, such as leaves of ""Acacia"" trees in the absence of these grasses.

More recently, addax were found from Algeria to Sudan, but due mainly to overhunting, they have become much more restricted and rare. Addax are easy to hunt due to their slow movements. Roadkill, firearms for easy hunting and nomadic settlements near waterholes (their dry-season feeding places) have also decreased numbers. Moreover, their meat and leather are highly prized. Other threats include chronic droughts in the deserts, habitat destruction due to more human settlements and agriculture. Fewer than 500 individuals are thought"
