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 da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Ape
The Hominidae (), whose members are known as the great apes or hominids (), are a taxonomic family of primates that includes eight extant species in four genera: '' Pongo'' (the Bornean, Sumatran and Tapanuli orangutan); ''Gorilla'' (the eastern and western gorilla); '' Pan'' (the chimpanzee and the bonobo); and ''Homo'', of which only modern humans remain. Several revisions in classifying the great apes have caused the use of the term ''"hominid"'' to vary over time. The original meaning of "hominid" referred only to humans (''Homo'') and their closest extinct relatives. However, by the 1990s humans, apes, and their ancestors were considered to be "hominids". The earlier restrictive meaning has now been largely assumed by the term ''" hominin"'', which comprises all members of the human clade after the split from the chimpanzees (''Pan''). The current meaning of "hominid" includes all the great apes including humans. Usage still varies, however, and some scientists a ...

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 sia ...

Western Hoolock Gibbon
The western hoolock gibbon (''Hoolock hoolock'') is a primate from the gibbon family, Hylobatidae. The species is found in Assam, Mizoram, and Meghalaya in India, Bangladesh, and Myanmar west of the Chindwin River. Classification Mootnick and Groves stated that hoolock gibbons do not belong in the genus ''Bunopithecus'', and placed them in a new genus, ''Hoolock''. This genus was argued to contain two and later three distinct species, which were previously thought to be subspecies: ''H. hoolock'', '' H. leuconedys'', and '' H. tianxing''. A larger evolutionary distance was later found to exist between these three species and the white-handed gibbons than between bonobos and chimpanzees. A new subspecies of the western hoolock gibbon has been described recently from northeastern India, which has been named the Mishmi Hills hoolock gibbon, ''H. h. mishmiensis''. Vocalisation Like other gibbons, hoolock gibbon pairs produce a loud, elaborate song, usually as a duet from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hoolock
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. Description Hoolocks are the second-largest of the gibbons, after the siamang. They reach a size of 60 to 90 cm and weigh 6 to 9 kg. The sexes are about the same size, but they differ considerably in coloration; males are black-colored with remarkable white brows, while females have a grey-brown fur, which is darker at the chest and neck. White rings around their eyes and mouths give their faces a mask-like appearance. The ''Oxford English Dictionary'' says that the name "hoolock" is from "a language of Assam." Distribution In northeast India, the hoolock is found south of Brahmaputra and the North Bank areas and east of the Dibang Rivers. Its range extends into seven states covering Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura (The seven northeastern states of ...

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.

Orangutan
Orangutans are great apes native to the rainforests of Indonesia and Malaysia. They are now found only in parts of Borneo and Sumatra, but during the Pleistocene they ranged throughout Southeast Asia and South China. Classified in the genus ''Pongo'', orangutans were originally considered to be one species. From 1996, they were divided into two species: the Bornean orangutan (''P. pygmaeus'', with three subspecies) and the Sumatran orangutan (''P. abelii''). A third species, the Tapanuli orangutan (''P. tapanuliensis''), was identified definitively in 2017. The orangutans are the only surviving species of the subfamily Ponginae, which diverged genetically from the other hominids (gorillas, chimpanzees, and humans) between 19.3 and 15.7 million years ago. The most arboreal of the great apes, orangutans spend most of their time in trees. They have proportionally long arms and short legs, and have reddish-brown hair covering their bodies. Adult males weigh about , while f ... [...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.

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 earl ...

Human
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus '' Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Ana ...

Gorilla
Gorillas are herbivorous, predominantly ground-dwelling great apes that inhabit the tropical forests of equatorial Africa. The genus ''Gorilla'' is divided into two species: the eastern gorilla and the western gorilla, and either four or five subspecies. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after chimpanzees and bonobos. Gorillas are the largest living primates, reaching heights between 1.25 and 1.8 metres, weights between 100 and 270 kg, and arm spans up to 2.6 metres, depending on species and sex. They tend to live in troops, with the leader being called a silverback. The Eastern gorilla is distinguished from the Western by darker fur colour and some other minor morphological differences. Gorillas tend to live 35–40 years in the wild. The oldest gorilla known is Fatou (b. 1957), who is still alive at the advanced age of 65 years. ...

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 a purely black fur, while the females have a 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 to be 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 ...
