This species is the most desert adapted of the gazelles and is found isolated pockets across the central Sahara Desert (Kingdom 1997, Spinage 1986). The extreme heat of this environment limited their feeding to the early morning and evening and G. leptoceros gains most of its water requirements from dew and plant moisture, relying little on open water sources. The slender-horned gazelle is a nomadic species moving across its desert range in search of vegetation, though it does not have a set migratory pattern (East 1997, Kingdom 1997).
