Gibbons are apes in the family Hylobatidae. The family historically contained one genus, but now is split into four extant genera and 20 species. Gibbons live in subtropical and tropical rainforest from eastern Bangladesh to Northeast India to southern China and Indonesia.
The lar gibbon, also known as the white-handed gibbon, is an endangered primate in the gibbon family, Hylobatidae. It is one of the better-known gibbons and is often kept in captivity.
The hoolock gibbons are three primate species of genus Hoolock in the gibbon family, Hylobatidae, native to eastern Bangladesh, Northeast India, Myanmar, and Southwest China.
The agile gibbon, also known as the black-handed gibbon, is an Old World primate in the gibbon family. It is found in Indonesia on the island of Sumatra, Malaysia, and southern Thailand. The species is listed as endangered on the IUCN Red List due to habitat destruction and the pet trade.
The silvery gibbon, also known as the Javan gibbon, is a primate in the gibbon family Hylobatidae. It is endemic to the Indonesian island of Java, where it inhabits undisturbed rainforests up to an altitude of 2,450 m (8,040 ft). It is listed as Endangered on the IUCN Red List since 2008, as the wild population is estimated at comprising less than 2500 mature individuals.
Kloss's gibbon, also known as the Mentawai gibbon, the bilou or dwarf siamang, is an endangered primate in the gibbon family, Hylobatidae. It is identifiable in that it is all black, resembling the siamang with its black fur, but is considerably smaller and lacks the siamang's distinctive throat pouch. Kloss's gibbon reaches a size 17 to 25 inches and weigh at most 13 pounds (6 kg). As is the case for all gibbons, they have long arms and no tail. Males and females are difficult to distinguish.
The genus Hylobates is one of the four genera of gibbons. Its name means "forest walker", from the Greek hūlē and bates.
Nomascus is the second-most speciose genus of gibbons. Originally, this genus was a subgenus of Hylobates, and all individuals were considered one species, Hylobates concolor. Species within Nomascus are characterized by 52 chromosomes. Some species are all black, some are light with a distinct black tuft of crown fur, and some have distinct, light-colored cheek patches. Nomascus is found from southern China (Yunnan) to southern Vietnam, and also on Hainan Island. One species, Nomascus nasutus, has been deemed "the most critically endangered ape species in the world". All species in this genus are either endangered or critically endangered.
The Hatinh langur is a highly threatened Old World monkey found in limestone forests in Vietnam, primarily in the Quảng Bình Province. A recent survey discovered a small population living in the Quảng Trị Province. Contrary to its name, it is not known from the Hà Tĩnh Province. The local Van Kieu minority refer to this lutung as the 'Con Cung', which roughly translates as "black, cliff-dwelling monkey with a long tail". It resembles the closely related François' langur, but its white cheek-stripes typically extend behind the ears onto the nape, and the overall black colour is non-glossy and has a brownish tinge.
The black crested gibbon is a Critically Endangered species of gibbon found in China, Laos, and northern Vietnam, with four subspecies.
The eastern black-crested gibbon, also known as the Cao-vit black crested gibbon or the Cao-vit crested gibbon, is a species of gibbon from southeast China and northern Vietnam. The term "Cao-vit" originated from the sounds of their calls or songs that villagers of Ngoc Khe, Phong Nam and Ngoc Con communes of Trung Khanh District, Cao Bang Province of Vietnam use to name for them. This name was officially used by gibbon experts since the rediscovery.
The northern white-cheeked gibbon is a Critically Endangered species of gibbon native to South East Asia. It is closely related to the southern white-cheeked gibbon, with which it was previously considered conspecific. The females of the two species are virtually indistinguishable in appearance.
The Indochinese black langur is a poorly known lutung native to Laos and adjacent Vietnam. It was originally described as a subspecies of T. auratus, but was later found to be a member of the T. francoisi group, with some maintaining it as a subspecies of that species. In 2001, it was recommended treating it as a separate species.
The Hainan black-crested gibbon or Hainan gibbon, is a Critically Endangered species of gibbon found only on Hainan Island, China. It was formerly considered a subspecies of the eastern black crested gibbon from Hòa Bình and Cao Bằng provinces of Vietnam and Jingxi County in Guangxi Zhuang Autonomous Region, China. Molecular data, together with morphology and call differences, suggest it is a separate species. Its habitat consists of broad-leaved forests and semi-deciduous monsoon forests. It feeds on ripe, sugar-rich fruit, such as figs and, at times, leaves, and insects.
The southern white-cheeked gibbon is a species of gibbon native to Vietnam and Laos. It is closely related to the northern white-cheeked gibbon and the yellow-cheeked gibbon ; it has previously been identified as a subspecies of each of these.
The Sumatran lar gibbon, also known as the Sumatran white-handed gibbon, is a subspecies of the lar gibbon, a primate in the gibbon family Hylobatidae. It is native to the island of Sumatra, Indonesia. It shares the tree tops with orangutans, which, like the gibbon, rarely come out of the trees due to predators, such as tigers and possibly sun bears.
The Myanmar snub-nosed monkey or Burmese snub-nosed monkey or black snub-nosed monkey is a critically endangered species of colobine monkey discovered in 2010 in northern Burma (Myanmar). It was formally described as a novel species of primate in 2011 based on its fur, beard and tail. Two groups of the species were discovered in China in 2011 and 2015, respectively.
Carpenter's lar gibbon is an endangered subspecies of white-handed gibbon, also known as the lar gibbon. It is listed as an endangered species because it is believed to have undergone a decline of more than 50% in the prior three generations due to loss of forest habitat and loss of mature individuals to hunting. The subspecific name honors primatologist Clarence R. Carpenter.
The central lar gibbon is is an subspecies of white-handed or lar gibbon that is vulnerable to extinction. It is endemic to Malaysia, Myanmar, and Thailand.
The Malaysian lar gibbon is is an endangered subspecies of white-handed or lar gibbon. It is endemic to Malaysia, and Thailand.
