The addax is a desert-living antelope and is well adapted to its harsh habitat. It feeds on desert grasses and scrub. It travels great distances over the Sahara Desert searching for sparse vegetation. It is the most desert-adapted of the antelopes. It spends most of its life without drinking water, receiving enough moisture to survive from the vegetation on which it feeds.
