Identification. The Central American Spider Monkey is a medium-sized primate. It is distinguished from other species by its cream-reddish-black body with very long, darker-colored limbs and a proportionately small head. Additionally, a pinkish mask of skin can be seen around the eyes and muzzle ( Wainwright and Arias 2007). This species is not easily confused with other primate species in the region.
