They are sexually dimorphic, as the females are smaller than the males. The head and body length in both sexes is 47” to 51”. The weight of males varies from 220 to 276 lbs, and that of females from 130 to 200 lbs.

The horns, which are found on both males and females, have two to three twists and are typically 22” to 31” in females and 28” to 33” in males, although the maximum recorded length is 43”.

Native Range Land:

Formerly, the Addax was widespread in the Sahelo-Saharan region of Africa, west of the Nile Valley and all countries sharing the Sahara Desert; but today the only known self-sustaining population is present in the Termit Massif Reserve (Niger). Native to Chad, Mauritania and Niger, the Addax was once abundant in North Africa but is now extinct in Algeria, Egypt, Libya, Sudan and the Western Sahara. It has been reintroduced into Morocco and Tunisia.
