Endangered
White-bellied spider monkey
Ateles belzebuth
White-bellied spider monkey is a New World monkey in the family Atelidae (order Primates) — Ateles belzebuth, recorded as Endangered.
Appearance
The white-bellied spider monkey, also known as the white-fronted or long-haired spider monkey, is an endangered species of spider monkey, a type of New World monkey. In the past, the Peruvian, brown and white-cheeked spider monkeys have been treated as subspecies of A. Belzebuth. As presently defined, the white-bellied spider monkey is monotypic.
Range and habitat
It is found in the north-western Amazon in Colombia, Ecuador, Venezuela, Peru and Brazil, ranging as far south as the lower Ucayali River and as far east as the Branco River. It has a whitish belly and a pale patch on the forehead, that, despite its common name, often is orange-buff, though this might be due to dirt and other stainers. Over the last 45 years (3 generations), the population has declined by approximately 50% due to habitat loss and hunting.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Females are usually more solitary than males, but females with dependent offspring are more likely to join a large group than those without dependent offspring. Copulations are initiated by females, and this pattern of greater female mate choice shared by other spider monkeys is believed to reduce aggression in males.
In crisis
Because of this, A. Belzebuth is listed as endangered by the IUCN.
CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
