The species faces issues with hunting and habitat loss, so is listed as Vulnerable on the IUCN Redlist. DescriptionThe red-faced spider monkey has long, black hair and a red or pink face that is bare except for a few short, white hairs.[4] Infants are born with dark faces, which lighten as they age.[4] Sexual dimorphism in the species is small; the head-body length of the male is {{convert|55.7|cm|in}} on average, while the female is around {{convert|55.2|cm|in|abbr=on}} in length.[4] The male weighs around {{convert|9.1|kg|lb|abbr=on}}, while the female weighs around {{convert|8.4|kg|lb|abbr=on}}.[2] The tail is prehensile (capable of grasping) and its fingers and limbs are long, agile and strong. BehaviorThe red-faced spider monkey exhibits a fission-fusion society, associating with large groups of up to 30 individuals during the night, but choosing to spend the days travelling, foraging, and resting in much smaller groups.[2][4] At dusk, they recongregate using a greeting call to communicate. At night, they often sleep in large groups called bands. Bands typically consist of several females, with their respective young, along with a few males for protection. The only range size estimate was {{convert|255|ha|acre}}, of which {{convert|220|ha|acre|abbr=on}} had suitable habitat.[2] The red-faced spider monkey feeds on a variety of foods and would be considered an omnivore. It will eat termites and grubs, but also feeds on supple leaves, flowers, berries and fruit. It has a gestation period of 226–232 days, is weaned after four or five years when it reaches sexual maturity, and has a life span of up to 33 years in captivity.[2][4] Habitat and distributionThe red-faced spider monkey is a habitat specialist, found in undisturbed primary rainforests,[4] in northern Brazil, Suriname, Guyana, French Guiana and Venezuela.[2] Because of its ability to climb and jump, it tends to live in the upper layers of the rainforest trees and forages in the high canopy.[4] ConservationThe red-faced spider monkey occurs in many protected area across its range,[2] and is protected in the Amazon under the Amazon Animal Protection Act of 1973. It is listed by the IUCN Red List as Vulnerable.[2] Further reading
