Hylobates Muelleri
The genus ''Hylobates'' is one of the four genera of gibbons. Its name means "forest walker", from the Greek (, "forest") and (, "one who treads"). It was once considered the only genus, but recently its subgenera (''Hoolock'' [formerly ''Bunopithecus''], ''Nomascus'', and ''Symphalangus'') have been elevated to the genus level. ''Hylobates'' remains the most species-rich and widespread of gibbon genera, ranging from southern China (Yunnan) to western and central Java (island), Java. Individuals within this genus are characterized by 44 chromosomes and often have a ring of white fur around their faces.

Müller's Gibbon
Müller's gibbon (''Hylobates muelleri''), also known as the southern grey gibbon, is a primate in the gibbon family, Hylobatidae. Taxonomy Formerly, the western grey gibbon (''H. abbotti'') and eastern grey gibbon (''H. funereus'') were considered conspecific with ''H. muelleri'', but more recent studies indicate that all three are distinct species, and both the IUCN Red List and the American Society of Mammalogists consider them such. Description Unlike most gibbon species, Müller's gibbon does not show sexual dimorphism in its fur coloration. Its fur is grey- or brown-colored with a ring of bright fur around its face. On the head, it often has a darkly colored cap. Weighing between 4–8 kg, it ranks among the smaller of the gibbons. Distribution and habitat Müller's gibbon is endemic to Kalimantan in the island of Borneo, inhabiting the southeastern part of the island. It is found approximately south of the Mahakam River and east of the Barito River. Behaviour So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomascus
''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.

Eastern Grey Gibbon
The eastern grey gibbon or northern grey gibbon (''Hylobates funereus'') is a primate in the gibbon family, Hylobatidae. Taxonomy Formerly, the eastern grey gibbon and western grey gibbon (''H. abbotti'') were considered conspecific with the southern grey gibbon (''H. muelleri''), but more recent studies indicate that all three are distinct species, and both the IUCN Red List and the American Society of Mammalogists consider them such. However, they can still hybridize with one another where their ranges meet. Distribution It is endemic to northeastern Borneo, and is found in Kalimantan, Sarawak, and Brunei. It ranges from Sabah south to the Mahakam River in East Kalimantan, and west to Baram in Sarawak. Conservation As with the other two grey gibbons, this species is thought to be endangered due to heavy deforestation in Borneo, as well as increases in forest fires exacerbated by El Niño El Niño (; ; ) is the warm phase of the El Niño–Southern Oscillation (EN ...

Bornean White-bearded Gibbon
The Bornean white-bearded gibbon (''Hylobates albibarbis''), also known as the Bornean agile gibbon or southern gibbon, is a species of gibbon endemic to southern Borneo. It is an endangered species, due to the undergoing logging of the tropical forests, between the Kapuas and Barito rivers. Additional issues are of concern to the endangerment of white-bearded gibbons and threatening to other arboreal primates. The white-bearded gibbon is very similar to other gibbons in their behaviour and their frugivorous diet. The Bornean white-bearded gibbon was formerly considered a subspecies of the agile gibbon but based on recent DNA research, some now classify it as a separate species.. p. 37. About The Bornean white-bearded gibbon is commonly seen with grey or dark brown fur, a black face, and white beard. Similar to other gibbons, these gibbons are a smaller ape that is tailless. They tend to live in small family groups consisting of a male, female, and their offspring. They exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yunnan Lar Gibbon
The Yunnan lar gibbon (''Hylobates lar yunnanensis''), also known as the Yunnan white-handed gibbon, is a subspecies of the lar gibbon, a primate in the gibbon family, Hylobatidae. This Chinese subspecies is thought to be extinct.Grueter et al. (2009). Are Hylobates lar Extirpated from China? International Journal of Primatology, 30:553–567online pdf Taxonomy This animal from Yunnan is listed as a distinct subspecies of the lar gibbon in recent taxonomic articles. However, there is still debate about the validity of this classification.Brandon-Jones, D., Eudey, A. A., Geissmann, T., Groves, C. P., Melnick, D. J., Morales, J. C., et al. (2004).

Sumatran Lar Gibbon
The Sumatran lar gibbon (''Hylobates lar vestitus''), 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.

Carpenter's Lar Gibbon
Carpenter's lar gibbon (''Hylobates lar carpenteri'') 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 subspecies is distinguished by sharply distinct dark and light color forms, both having a ring of white hair around the face, with hands and feet white sometimes as far as the wrists and ankles, and the hair much longer than in other subspecies. The dark form is very dark chocolate brown, the tips of the hairs being blackish and their bases silvery-brown, whereas the light form is creamy-white, with the basal one-quarter to one-third of the hairs light gray. Its range is confined to northern and part of northeastern Thailand. In the southwest part of its range, its distri ... [...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] |
