The gray woolly monkey (Lagothrix lagothricha cana) or Geoffroy's woolly monkey is a subspecies of the common woolly monkey from South America. It is found in Bolivia, Brazil and Peru. L. l. cana gets its common name, gray woolly monkey, from its thick gray coat. Its hands, feet, face and the inside of the arms are dark in color. [3] The gray woolly monkey has been considered endangered by IUCN since 2008. The subspecies is listed as endangered because it suffered a 50% decrease in population over the past 45 years due to deforestation and hunting. [2]
Initially thought to be a subspecies of the common woolly monkey (L. lagothricha), it was later reclassified as its own species. Two subspecies of Lagothrix cana were known: L. c. cana and L. c. tschudii. L. c. cana in both Brazil and Peru and L. c. tschudii in southeastern Peru and in the Madidi National Park in Bolivia. However, a 2014 study supported reclassifying it again within L. lagothrica, with both subspecies being different subspecies of L. lagothrica. [2] [4] [5] [6]
The gray woolly monkey predominantly lives in cloud forest, a type of forest under cloud cover for most of the year. They can be found anywhere from 1,000 to 2,500 metres above sea level. The population of gray woolly monkeys in Bolivia have been reported to be found as low as 700 metres above sea level. [4] They spend the majority of their time high in the tree tops in search of food. [7] They move through the trees using their large prehensile tails, which is a common trait seen in the family Atelidae. [8] They are capable of hanging from their tails and often use them to bridge gaps between trees when travelling in them. [9]
The gray woolly monkey predominantly eats fruit, but occasionally when fruit is scarce will eat young leaves and sometimes seeds. [7]
Gray woolly monkeys live in groups of 11 to 25 members. These groups are of both mixed ages and sexes. [8] The group will move together and show little aggression towards other groups, and will often share the best feeding spots with other groups. [3]
In general, males are larger than females. A male's head-body length ranges from 46 to 65 cm in length. A female's head-body length ranges from 46 to 58 cm in length. The tail length of the gray woolly monkey is on average from 66 to 68 cm in length. [3] The male gray woolly monkey weighs an average of 9.5 kg. The female gray woolly monkey weighs an average of 7.7 kg. [10]
The main threat the subspecies faces is hunting. They are hunted for food and pets. The females are often targeted for hunting as they are shot and then their offspring are taken and sold as pets. One story from the western Amazon reported several hunters who killed over 200 woolly monkeys in less than two years, which led to their local extinction. Deforestation is another major threat. Mining for cassiterite, a mineral used to make tin, is also a threat for both losing habitat and hunting. [11]
The gray woolly monkey is currently protected in many national parks. [2] They are also listed in Appendix II of the Convention on International Trade of Endagenered Species (CITES). [12] The following is a list of protected areas in Brazil where the gray woolly monkey occurs or may occur. [2]
The entire known population of these monkeys in Bolivia are found in the Apolobamba Natural Area of Integrated Management and the Madidi National Park and Natural Area of Integrated Management. [2]
The woolly monkeys are the genus Lagothrix of New World monkeys, usually placed in the family Atelidae.
The Atelidae are one of the five families of New World monkeys now recognised. It was formerly included in the family Cebidae. Atelids are generally larger monkeys; the family includes the howler, spider, woolly, and woolly spider monkeys. They are found throughout the forested regions of Central and South America, from Mexico to northern Argentina.
Spider monkeys are New World monkeys belonging to the genus Ateles, part of the subfamily Atelinae, family Atelidae. Like other atelines, they are found in tropical forests of Central and South America, from southern Mexico to Brazil. The genus consists of seven species, all of which are under threat; the brown spider monkey is critically endangered. They are also notable for their ability to be easily bred in captivity.
The Atelinae are a subfamily of New World monkeys in the family Atelidae, and includes the various spider and woolly monkeys. The primary distinguishing feature of the atelines is their long prehensile tails, which can support their entire body weight.
The Madidi titi monkey, also known as the GoldenPalace.com monkey or the golden palace monkey, is a titi, a kind of New World monkey, discovered in western Bolivia's Madidi National Park in 2004. Its scientific name is Plecturocebus aureipalatii, the specific epithet meaning "of the Golden Palace", in reference to GoldenPalace.com, an online casino which paid US$650,000 to have the species named after it, with benefits going toward the nonprofit organization that maintains the park where the titi was discovered.
The common woolly monkey, brown woolly monkey, or Humboldt's woolly monkey is a woolly monkey from Colombia, Ecuador, Peru, Bolivia, Brazil, and Venezuela. It lives in groups of two to 70 individuals, usually splitting the group into smaller subgroups when active.
The collared titi monkey is a species of titi, a type of New World monkey. It is endemic to northern Brazil.
The Colombian woolly monkey is a critically endangered subspecies of the common woolly monkey from Colombia.
The silvery woolly monkey, also known as Poeppig's woolly monkey or the red woolly monkey, is a subspecies of the common woolly monkey from South America. Named after the German zoologist Eduard Friedrich Poeppig, it is found in Brazil, Ecuador and Peru.
Geoffroy's spider monkey, also known as the black-handed spider monkey or the Central American spider monkey, is a species of spider monkey, a type of New World monkey, from Central America, parts of Mexico and possibly a small portion of Colombia. There are at least five subspecies. Some primatologists classify the black-headed spider monkey (A. fusciceps), found in Panama, Colombia, and Ecuador as the same species as Geoffroy's spider monkey.
The Peruvian spider monkey, also known as the black-faced black spider monkey, is a species of spider monkey that lives in Peru, as well as in Brazil and in Bolivia. At 60 centimetres long, they are relatively large among species of monkey, and their strong, prehensile tails can be up to 1 m (3 ft) long. Unlike many species of monkey, they have only a vestigial thumb, an adaptation which enables them to travel using brachiation. Peruvian spider monkeys live in groups of 20–30 individuals, but these groups are rarely all together simultaneously. The size and dynamics of the resulting subgroups vary with food availability and sociobehavioral activity. They prefer to eat fleshy fruit, but will change their diet in response to scarcity of ripe fruit. Individuals of this species also eat small animals, insects and leaves based on availability. Females separate from the band to give birth, typically in the fall. These females inhabit a group of core areas where resources are abundant in certain seasons. Typically, males exhibit ranging over longer distances than females, with movement of individuals enhancing the fluidity of subgroup size. Peruvian spider monkey are independent at about 10 months, with a lifespan of about 20 years.
Azara's night monkey, also known as the southern night monkey, is a night monkey species from South America. It is found in Argentina, Bolivia, Brazil, Peru and Paraguay. The species is monogamous, with the males providing a large amount of parental care. It is named after Spanish naturalist Félix de Azara. Although primarily nocturnal, some populations of Azara's night monkey are unique among night monkeys in being active both day and night. The species is listed as Least Concern on the IUCN Red List.
The Yucatán black howler, or Guatemalan black howler, is a species of howler monkey, a type of New World monkey, from Central America. It is found in Belize, Guatemala and Mexico, in and near the Yucatán Peninsula. It lives in evergreen, semideciduous and lowland rain forests. It is also known as the baboon in Belize, although it is not closely related to the baboons in Africa.
The yellow-tailed woolly monkey is a New World monkey endemic to Peru. It is a rare primate species found only in the Peruvian Andes, in the departments of Amazonas and San Martin, as well as bordering areas of La Libertad, Huánuco, and Loreto.

The Southwest Amazon moist forests (NT0166) is an ecoregion located in the Upper Amazon basin.
The Juruá–Purus moist forests (NT0133) is an ecoregion in northwest Brazil in the Amazon biome. The terrain is very flat and soils are poor. The rivers flood annually. There are no roads in the region, and the dense rainforest is relatively intact, although plans to extend the Trans-Amazonian Highway through the region would presumably cause widespread damage to the habitat.
Collins' squirrel monkey is a species of squirrel monkey endemic to Brazil. It had been considered a subspecies of the common squirrel monkey until a genetic study by Jessica Lynch Alfaro et al. elevated it to species status.
