Ateles fusciceps (brown-headed spider monkey)

Wikipedia Abstract

The black-headed spider monkey (Ateles fusciceps) is a species of spider monkey, a type of New World monkey, from Central and South America. It is found in Colombia, Nicaragua and Panama. Although primatologists such as Colin Groves (1989) follow Kellogg and Goldman (1944) in treating A. fusciceps as a separate species, other authors, including Froelich (1991), Collins and Dubach (2001) and Nieves (2005) treat it as a subspecies of Geoffroy's spider monkey. The two subspecies are: Captive black-headed spider monkeys have been known to live more than 24 years. \n* \n*

EDGE Analysis

This species is highly suspensory and is usually only found in the canopy. They are further adapted to their arboreal lifestyle by lacking a thumb, which increases the strength of their grip for climbing. Their reliance on primary forest has meant that this species has suffered greatly from continued habitat loss. Furthermore, their slow rate of reproduction makes them susceptible to hunting pressure. The brown-headed spider monkey is one of the most threatened animals in Ecuador. Two subspecies of the brown-headed spider monkey are recognised, with each living in a different area. The subspecies Ateles fusciceps fusciceps occurs in Ecuador, while the range of Ateles fusciceps rufiventris (Colombian black spider monkey) extends from south-western Colombia to eastern Panama.
