White-cheeked Gibbon
''Nomascus'' is the second-most speciose genus of gibbons (family Hylobatidae). 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.

Northern White-cheeked Gibbon
The northern white-cheeked gibbon (''Nomascus leucogenys'') is a Critically Endangered species of gibbon native to South East Asia. It is closely related to the southern white-cheeked gibbon (''Nomascus siki''), with which it was previously considered conspecific. The females of the two species are virtually indistinguishable in appearance. The genome of ''N. leucogenys'' was sequenced and published in 2011. Description Northern white-cheeked gibbons are sexually dimorphic, with males and females having different colourations and the former also being slightly larger. Males have black hair over their entire bodies, except for distinct white patches on their cheeks, as well as a prominent tuft of hair on the crown of head, and a gular sac. Females are reddish-tan in colour, lack a cranial tuft, and have a crest of black or dark brown fur running from the crown to the nape of the neck. They are reported to have an average weight of , although this is based on only a small number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hylobatidae
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 (including the islands of Sumatra, Borneo and Java). Also called the lesser apes, gibbons differ from great apes ( bonobos, chimpanzees, gorillas, orangutans and humans) in being smaller, exhibiting low sexual dimorphism, and not making nests. Like all apes, gibbons are tailless. Unlike most of the great apes, gibbons frequently form long-term pair bonds. Their primary mode of locomotion, brachiation, involves swinging from branch to branch for distances up to , at speeds as fast as . They can also make leaps up to , and walk bipedally with their arms raised for balance. They are the fastest of all tree-dwelling, nonflying mammals. Depending on the species and sex, gibbons' fur coloration varies from dar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primate Genera
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large brai ...

Mammals Of Southeast Asia
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

Northern Buffed-cheeked Gibbon
The northern buffed-cheeked gibbon (''Nomascus annamensis'') is a newly discovered species of crested gibbon which is found in Vietnam, Cambodia, and Laos. Its habitat is in the humid subtropical and seasonal tropical forests of these countries. Description The northern buffed-cheeked gibbon resembles ''Nomascus gabriellae'' in appearance.Thinh, Van Ngoc, Alan R. Mootnick, Vu Ngoc Thanh, Tilo Nadler and Christian Roos, Van Ngoc Thinh, Alan R. Mootnick, Vu Ngoc Thanh, Tilo Nadler and Christian Roos. "A new species of crested gibbon, from the central Annamite mountain range". ''Vietnamese Journal of Primatology''. Vol 1. No. 4. Males and females of ''N. annamensis'' differ in morphology and color. The male has a primarily black pelt that glistens silver in sunlight, with a lighter brown chest. The cheeks are a deep golden-orange, and the crest is very prominent. The female, though, lacks the characteristic crest and is orange-beige in color. The holotype A holotype is a sing ...

Yellow-cheeked Gibbon
The yellow-cheeked gibbon (''Nomascus gabriellae''), also called the golden-cheeked gibbon, the yellow-cheeked crested gibbon, the golden-cheeked crested gibbon, the red-cheeked gibbon, or the buffed-cheeked gibbon, is a species of gibbon native to Vietnam, Laos, and Cambodia. The species was discovered and named after the British naturalist Gabrielle Maud Vassal. The yellow-cheeked gibbon is born blond and later turns black. Males carry this colouring through their lifespan and have the distinguishing golden cheeks. Females are born blonde to blend into their mother's fur but they later turn black. Females turn back to blond at sexual maturity, keeping only a black cap on the top of their heads. This diurnal and arboreal gibbon lives in primary tropical forest, foraging for fruits, using brachiation to move through the trees. Little is known about this species in the wild, but it is thought that it has a life span of approximately 46 years. Gibbon groups vocalise loudly early ...

Southern White-cheeked Gibbon
The southern white-cheeked gibbon (''Nomascus siki'') is a species of gibbon native to Vietnam and Laos. It is closely related to the northern white-cheeked gibbon (''Nomascus leucogenys'') and the yellow-cheeked gibbon (''Nomascus gabriellae''); it has previously been identified as a subspecies of each of these. Description and habitat Members of the species are not a uniform colour; unweaned juveniles are a light brown, turning to black after weaning. Adult males remain black, but adult females are brown. The name of the species is taken from the male's facial markings, a large patch of white fur around the edge of the mouth - this distinguishes it from a male of ''N. leucogenys'', which has the white in a streak along the cheeks. Females have a thin edging of white around the face.Groves, Colin. ''Speciation and biogeography of Vietnam’s primates''.

Hainan Black Crested Gibbon
The Hainan black-crested gibbon or Hainan gibbon (''Nomascus hainanus''), 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 (''Nomascus nasutus'') 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. Current status Hainan black-crested gibbons are under grave threat of extinction. They are currently identified as critically endangered on the International Union for Conservation of Nature’s Red List. Historically, they were widespread in China: Government records dating back to the 17th century state that their range used to cover half of China, altho ...

Eastern Black Crested Gibbon
The eastern black-crested gibbon (''Nomascus nasutus''), also known as the Cao-vit black crested gibbon or the Cao-vit crested gibbon, is a species of gibbon 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 ... 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. From the 1960s until the 2000s there had been no confirmed sightings of the eastern black-crested gibbon and it was thought to be possibly extinct. In 2002 a small population was rediscovered by two Fauna and Flora International, FFI biologists in a karst forest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Symphalangus
The siamang (, ; ''Symphalangus syndactylus'') is an arboreal, black-furred gibbon native to the forests of Indonesia, Malaysia, and Thailand. The largest of the gibbons, the siamang can be twice the size of other gibbons, reaching in height, and weighing up to . It is the only species in the genus ''Symphalangus''. Fossils of siamangs dates back to the Middle Pleistocene. Two features distinguish the siamang from other gibbons. First, two digits on each foot—the second and third toes—are partially joined by a membrane, hence the specific name '' syndactylus'', from the Ancient Greek σύν, ''sun-'', "with" + δάκτυλος, ''daktulos'', "finger". Second, a large gular sac (throat pouch), found in both males and females of the species, can be inflated to the size of the siamang's head, allowing it to make loud, resonating calls or songs. Two subspecies of the siamang may exist. If so, they are the nominate Sumatran siamang (''S. s. syndactylus'') and the Malaysian siama ...
