Hylobates
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'' ormerly ''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. Individuals within this genus are characterized by 44 chromosomes and often have a ring of white fur around their faces.

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 forests from eastern Bangladesh and Northeast India to Southeast Asia and Indonesia (including the islands of Sumatra, Borneo and Java). Also called the lesser apes, gibbons differ from the great apes ( chimpanzees, gorillas, orangutans and humans) in being smaller, exhibiting low sexual dimorphism, and not making nests. Like all of the 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hylobatidae
Gibbons () are apes in the Family (biology), 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 forests from eastern Bangladesh and Northeast India to Mainland Southeast Asia, Southeast Asia and Indonesia (including the islands of Sumatra, Borneo and Java (island), Java). Also called the lesser apes, gibbons differ from the great apes (pan (genus), chimpanzees, gorillas, orangutans and humans) in being smaller, exhibiting low sexual dimorphism, and not making nests.

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 ongoing logging of tropical forests between the Kapuas and Barito rivers. Additional issues of concern to the endangerment of white-bearded gibbons also threaten 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. Description and life history 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. T ...

Agile Gibbon
The agile gibbon (''Hylobates agilis''), also called the black-handed gibbon, is an Old World primate, and is a part of the gibbon family. It is native to Indonesia, specifically, on the island of Sumatra. The agile gibbon can also be found in Malaysia, and southern Thailand. As appointed by the IUCN Red List, this species is endangered, and mainly due to the destruction of their habitat and pet trade. Taxonomy The species is generally thought not to have subspecies, but some experts recognise a mountain form and a lowland form. * Mountain agile gibbon, ''Hylobates agilis agilis'' * Lowland agile gibbon, ''Hylobates agilis unko'' Description The agile gibbon has fur varying in color from black to red-brown. The brow is white, and the male can be recognized by his white or light-grey cheeks. Additionally, the male is slightly larger than the female. The agile gibbon weighs from with an average of , though in captivity it can reach . It has a head and body length of . Like all g ...

Hylobates Moloch
The silvery gibbon (''Hylobates moloch''), 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 . It has been listed as Endangered on the IUCN Red List since 2008, as the wild population is estimated to comprise less than 2500 mature individuals. Its coat is bluish-grey, with a dark grey or black cap. Like all gibbons, the silvery gibbon lacks an external tail, has dorsally placed scapulae, and reduced flexibility in its lumbar region. It has long, curved fingers and very long forelimbs relative to its hind limbs. On average, it reaches in weight. It is diurnal and arboreal, climbing trees skilfully and brachiating through the forests. Brachiation is possible because of its mobile wrist joints, full rotation of the upper arm, and the ability to lock elbows in suspension. Its diet consists of fruits, leaves, and flowers. Every three years, on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pileated Gibbon
The pileated gibbon (''Hylobates pileatus'') is a primate in the gibbon family, Hylobatidae. The pileated gibbon has sexual dimorphism in fur coloration: males have purely black fur, while females have white-grey colored fur with only the belly and head black. The white and often shaggy hair ring around the head is common to both sexes. The species has been identified as endangered and is listed in CITES Appendix I. Their main threat is habitat destruction, with the wild forest they live in being converted into farmland. This has led to local extinction in some areas. Also, like many other species of primate, they are hunted and captured for meat and sold into Wildlife smuggling. Many attempts have been made to survey and increase the species' numbers, both concerning their status in the wild, and in zoos. Range The range of the pileated gibbon is eastern Thailand, western Cambodia and southwest Laos. Its lifestyle is much like other gibbons: diurnal and arboreal, it lives toge ...

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 bear The sun bear (''Helarctos malayanus'') is a bear species in the Family (biology), family Ursidae found in the tropical forests of Southeast Asia. It is the only species in the genus ''Helarctos'' and the smallest bear species, standing nearly ...s.
