Lagothrix
The woolly monkeys are the genus ''Lagothrix'' of New World monkeys, usually placed in the family Atelidae. Both species in this genus originate from the rainforests of South America. They have prehensile tails and live in relatively large social groups. Taxonomy The following 2 species and 5 subspecies are currently considered to be within the genus: *Yellow-tailed woolly monkey, ''L. flavicauda'' (formerly placed in genus ''Oreonax'') * Common woolly monkey, ''L. lagothricha'' ** Gray woolly monkey, ''L. l. cana'' **Brown woolly monkey, ''L. l. lagothricha'' ** Colombian woolly monkey, ''L. l. lugens'' ** Silvery woolly monkey, ''L. l. poeppigii'' ** Peruvian woolly monkey, ''L. l. tschudii'' Description Woolly monkeys are closely related to spider monkeys. They have a thick brown coat with dark gray appendages. The stomach area is black and heads are light brown. The fur color is the same for both males and females. Variation in color exist among subspecies. A prehensile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Woolly Monkey
The common woolly monkey, brown woolly monkey, or Humboldt's woolly monkey (''Lagothrix lagothricha'') 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. Taxonomy The taxonomy of the common woolly monkey is still debated. Fooden classified it is as one of two species under the genus ''Lagothrix'' with four sub-species (''L. l. lagotricha'', ''L. l. lugens'', ''L. l. cana'', and ''L. l. poeppgigii''. Later, an analysis of craniodental morphology suggested a move of all sub-species to the species level and also led to the yellow-tailed woolly monkey (formerly ''Lagothrix flavicauda'') being moved to a monotypic genus ''Oreonax''. Genetic analyses also identify distinct groups, but different groupings from morphological and molecular data continue to make this a difficult issue that might be addressed with larger data sets. A 2014 study found the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Silvery Woolly Monkey
The silvery woolly monkey (''Lagothrix lagothricha poeppigii''), 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. Taxonomy It was initially thought to be a subspecies of the common woolly monkey (''L. lagothricha''), but was later reclassified as its own species. However, a 2014 phylogenetic study found it to in fact be a subspecies of ''L. lagothricha''; the results of this study have been followed by the American Society of Mammalogists and the IUCN Red List. Habitat Silvery woolly monkeys are habituated across the Amazonia, and are found in mature closed-canopy rainforest. Dispersal Traditionally, silvery woolly monkeys have a male philopatry and female-biased dispersal. However, recent analysis of genetic data in ''L. poeppigii'' suggests that female-biased dispersal may not be strictly follow ...

Lagothrix Flavicauda
The yellow-tailed woolly monkey (''Lagothrix flavicauda'') 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. Taxonomy The yellow-tailed woolly monkey was at first classified in the genus ''Lagothrix'' along with other woolly monkeys, but due to debatable primary sources, it was later placed in its own monotypic genus, ''Oreonax''. ''Oreonax'' has been proposed to be a subgenus of ''Lagothrix'', but others have regarded it as a full genus. A recent extensive study suggests that the yellow-tailed woolly monkey indeed belongs in ''Lagothrix'', which has been followed by the American Society of Mammalogists and the IUCN Red List. Discovery and rediscovery The species was first described by Alexander von Humboldt in 1812 under the name ''Simia flavicauda'', based on a skin found 10 years earlier, used by a local man ...

Gray Woolly Monkey
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.Rowe, N. (1996) ''The Pictorial Guide to the Living Primates.'' Pogonias Press, Rhode Island. . 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. Taxonomy 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colombian Woolly Monkey
The Colombian woolly monkey (''Lagothrix lagothricha lugens'') is a critically endangered subspecies of the common woolly monkey from Colombia. It was initially thought to be a subspecies of the common woolly monkey (''L. lagothricha''), but was later reclassified as its own species. However, a 2014 phylogenetic study found it to in fact be a subspecies of ''L. lagothricha''; the results of this study have been followed by the American Society of Mammalogists and the IUCN Red List. Among all Atelinae, ateline primates, Colombian woolly monkeys exhibit the most sexual dimorphism in body size. Males are about forty-five percent heavier than their female counterparts. However, the cause of this dimorphism remains an enigma as there are no apparent female choice in favor of larger males. In fact, mating amongst Colombian woolly monkeys is promiscuous in that all adult and subadult males in a group mate with each female in estrous, and male-male rivalries in the context of mating are ...

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 (the latter being the largest of the New World monkeys). They are found throughout the forested regions of Central and South America, from Mexico to northern Argentina. Characteristics The Atelidae family consists of monkeys that are small to moderate in size, usually 34 to 72 cm in head-body length, with the howler monkeys being the largest members of the group, and the spider monkeys being the smallest. They have long prehensile tails with a sensitive, almost hairless, tactile pad on the underside of the distal part. The tail is frequently used as 'fifth limb' while moving through the trees where they make their homes. They also have nails on their fingers and toes, enabling them to climb. Most species have predominantly dark brown, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woolly Monkey Hepatitis B Virus
The ''woolly monkey hepatitis B virus'' (WMHBV) is a viral species of the ''Orthohepadnavirus'' genus of the ''Hepadnaviridae'' family. Its natural host is the woolly monkey (''Lagothrix)'', an inhabitant of South America categorized as a New World primate. WMHBV, like other hepatitis viruses, infects the hepatocytes, or liver cells, of its host organism. It can cause hepatitis, liver necrosis, cirrhosis, and hepatocellular carcinoma (liver cancer). Because nearly all species of ''Lagothrix'' are threatened or endangered, researching and developing a vaccine and/or treatment for WMHBV is important for the protection of the whole woolly monkey genus. WMHBV is also of great interest to researchers because of its potential to teach us more about the human hepatitis B virus (HBV). WMHBV is a distant phylogenetic sister species to human HBV, although the evolutionary history of hepatitis B viruses is not well understood. Additionally, WMHBV was the first hepadnavirus other than huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider Monkey
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 consistes 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. Disproportionately long limbs and long prehensile tails make them one of the largest New World monkeys and give rise to their common name. Spider monkeys live in the upper layers of the rainforest, and forage in the high canopy, from . They primarily eat fruits, but will also occasionally consume leaves, flowers, and insects. Due to their large size, spider monkeys require large tracts of moist evergreen forests, and prefer undisturbed primary rainforest. They are social animals and live in bands of up to 35 individuals, but will split up to forage during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
