Adax (Sp), Mendesantilope (G), Addax (F).
DESCRIPTION (male) Shoulder height 40-45 inches (102-115 cm). Weight 200-275 pounds (90-125 kg).
A relative of the oryxes, the addax is a medium-sized, heavily built antelope, with horns (both sexes) that are long, spirally twisted (up to almost three turns), divergent and prominently ringed. Overall color is sandy-gray, with underparts and legs white. There is a dark-brown patch on the forehead and a white patch across the muzzle in front of the eyes. The tail is fairly long with a black tuft. Hoofs are enlarged and widely splayed for walking on desert sand. Females are similar to males, though somewhat smaller, and have shorter, thinner horns.
DISTRIBUTION Private ranches, mainly in Texas but also in several other U.S. states.
REMARKS Once widespread throughout the Sahara Desert and adjoining semi-desert areas in North Africa, but now exterminated in most areas from uncontrolled hunting. Listed as endangered in its native habitat. Private herds exist in various parts of the world.
March 19, 2014 – The 2005 regulation that authorizes certain otherwise prohibited activities under the Endangered Species Act (ESA) with U.S. captive-bred animals and sport-hunted trophies of the scimitar-horned oryx, addax and dama gazelle has been reinstated. Individuals who wish to take part in otherwise prohibited activities, including interstate or foreign commerce, import, export, culling or other forms of take, that meet the criteria for enhancement of these species under the ESA may do so without obtaining a permit.
HYBRIDIZATION The addax is either known or believed to crossbreed, or to be the result of hybridization, when in a game ranch environment.
