Sooty mangabeys are diurnal old world monkeys located on the west coast of Africa (McGraw, 1998; Groves, 2001).

Sooty mangabey pelage color varies from gray to brown gray. Their faces are grayish pink with darker muzzle and ears (Groves, 2001). They are also sexual dimorphic with males nearly twice the size of the females (10.2 kg vs 5.5 kg) (Harvey and Clutton-Brock, 1985).

Sooty mangabey habit is mainly high forests of West Africa and the tropical evergreen rainforest located in Côte d’lvoire (McGraw, 1998; Range and Noë, 2002; McGraw et al. 2007). They have also been found in old growth forest and secondary forests (Fimbel, 1994).

Sooty mangabeys are terrestrial (McGraw, 1996). Their main movement is quadrupedal (McGraw, 1998). During climbing and leaping they tend to remain in the understory, shrub layer or ground (McGraw, 1998). When they rest they avoid sitting on the ground and rather sit on fallen branches and other items on the ground (McGraw, 1996)

Sooty mangabeys diet includes fruits, seeds and invertebrate (McGraw, 1998; Rödel et al., 2002). They also regularly eat frog eggs and appear to actively seek them out for eating (Rödel et al., 2002).

Sooty mangabeys live in large groups of multimales and females (Range & Noë, 2002). Males will either be full time residents or transient residents (Range, 2005). Male disperse while females are philopatric (Range, 2006). Both males and females have a linear dominance hierarchy (Range & Noë, 2002; Range 2006).

Female soot mangabeys have sexual swellings during ovulation (Gust, 1995b). Generally the highest-ranking male will attempt to monopolize the females however sneak copulations do occur. Gestation occurs over approximately 167 days (Gust et al. 1990).
