Slender-horned gazelle  (Gazella leptoceros)

Once the most common gazelle in the Sahara Desert, the slender-horned gazelle suffered serious decline in the 1970s, leaving its populations highly fragmented (3). It is found in low numbers across Algeria, Chad, Egypt, Libya, Mali, Niger, Sudan and Tunisia (1), but its presence in the more southern Saharan countries in this list has been unverified for many years (7).

Inhabits sandy and stony deserts with acacia groves and sandy depressions with sparse vegetation (3). Most known populations are associated with the major Saharan sand seas of the western desert (Egypt to Libya), the Erg Oriental and Erg Occidental (Tunisia and Algeria) (7).
