Animal Behavior: The addax moves about the desert in herds of about 5 - 20 animals. The herd is led by a dominant adult male. Females establish a hierarchy of dominance with the oldest animals ranking the highest. The addax is a short leg runner. It cannot achieve very high running speeds, allowing it to fall prey to faster predators.

Eating Habits: The addax feeds on desert grasses and scrub. They search great distances through the Sahara for sparse vegetation.

Range: The current range reduced to desert regions in Northeastern Niger, North Central Chad, Northwestern Mali, Eastern Mauritania, Southern Libya, and Northwestern Sudan.

Conservation Status: Addax are heavily built, slow running antelopes that are easy prey for humans with modern weapons. Hunting has decreased and eliminated many resident populations in many parts of its original range. They are listed on the IUCN Red List as Critically Endangered.

Animal Facts: Addaxes can live up to 25 years in captivity. The average number of offspring is 1 calf. The meat and skin of the addax are highly prized by locals, who use the hides for shoes and sandal soles.
