Semnopithecus
Gray langurs, also called Hanuman langurs and Hanuman monkeys, are Old World monkeys native to the Indian subcontinent constituting the genus ''Semnopithecus''. Traditionally only one species ''Semnopithecus entellus'' was recognized, but since about 2001, additional species have been recognized. The taxonomy has been in flux, but currently eight species are recognized. Gray langurs are fairly terrestrial, inhabiting forest, open lightly wooded habitats, and urban areas on the Indian subcontinent. Most species are found at low to moderate altitudes, but the Nepal gray langur and Kashmir gray langur occur up to in the Himalayas. Characteristics These langurs are largely gray (some more yellowish), with a black face and ears. Externally, the various species mainly differ in the darkness of the hands and feet, the overall color and the presence or absence of a crest. Typically all north Indian gray langurs have their tail tips looping towards their head during a casual walk where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tufted Gray Langur
The tufted gray langur (''Semnopithecus priam''), also known as Madras gray langur, and Coromandel sacred langur, is an Old World monkey, one of the species of langurs. This, like other gray langurs, is mainly a leaf-eating monkey. It is found in southeast India and Sri Lanka. It is one of three ''Semnopithecus'' species named after characters from ''The Iliad'', '' S. hector'' and '' S. ajax'' being the others. In Sinhala it is known as හැලි වදුරා (''Heli wandura''). Taxonomy and evolution There are two subspecies, ''Semnopithecus priam priam'' in India, and ''Semnopithecus priam thersites'' from Sri Lanka. There are two theories about the evolution of these two subspecies. According to one theory, ''Semnopithecus priam'' arose from subspecies '' Semnopithecus vetulus philbricki''. With the glacial fluctuations, and far apart of Indian subcontinent, pushed two taxa apart, but both retained key adaptation to folivory, and a ruminant-like stomach. Thereafter, ...

Purple-faced Langur
The purple-faced langur (''Semnopithecus vetulus''), also known as the purple-faced leaf monkey, is a species of Old World monkey that is endemic to Sri Lanka. The animal is a long-tailed arboreal species, identified by a mostly brown appearance, dark face (with paler lower face) and a very shy nature. The species was once highly prevalent, found in suburban Colombo and the "wet zone" villages (areas with high temperatures and high humidity throughout the year, whilst rain deluges occur during the monsoon seasons), but rapid urbanization has led to a significant decrease in the population level of the monkeys. It had traditionally been classified within the lutung genus ''Trachypithecus'' but was moved to the genus ''Semnopithecus'' based on DNA evidence indicating that is it more closely related to the gray langurs. In Sinhala it is known as ශ්රී ලංකා කළු වඳුරා ʌlu vʌⁿðura(Sri Lanka black monkey). Description In the purple-faced lang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northern Plains Gray Langur
The northern plains gray langur (''Semnopithecus entellus''), also known as the sacred langur, Bengal sacred langur and Hanuman langur, is a species of primate in the family Cercopithecidae. Taxonomy The northern plains gray langur belongs to the genus ''Semnopithecus'' along with the other Indian langurs. The southern plains gray langur was once classified as a subspecies of ''S. entellus'', i.e., ''S. entellus dussumieri'' and later regarded as a separate species, i.e., ''S. dussumieri'', but is now regarded as an invalid taxon. Most of the specimens that had been regarded as ''Semnopithecus dussumieri'' fall within the revised range of ''Semnopithecus entellus''.

Kashmir Gray Langur
The Kashmir gray langur (''Semnopithecus ajax'') is an Old World monkey, one of the langur species. It is a leaf-eating monkey. It has been reported from Jammu and Kashmir and Himachal Pradesh in northwestern India but evidence indicates it only occurs in the Chamba Valley in Himachal Pradesh. Because of its restricted range, fragmented population and threats from human agriculture and development activities it is listed as Endangered in the IUCN Red List. In Pakistan it occurs in Machiara National Park. It was formerly considered a subspecies of '' Semnopithecus entellus'' and is one of several ''Semnopithecus'' species named after characters from ''The Iliad'', along with '' Semnopithecus hector'' and '' Semnopithecus priam''. Ecology and behaviour It is arboreal and diurnal, and lives in temperate and alpine forests at elevations between . The birthing season for the Kashmir gray langur runs from January through June, although almost half of all infants are born in Marc ...

Black-footed Gray Langur
The black-footed gray langur (''Semnopithecus hypoleucos'') is an Old World monkey, one of the species of langurs. Found in southern India, this, like other gray langurs, is a leaf-eating monkey. Taxonomy The black-footed gray langur was previously considered to be a subspecies of '' Semnopithecus entellus''. Research done in 2003 by Brandon-Jones may indicate that it is a subspecies of '' Semnopithecus dussumieri''. Some experts believe that the species may be a naturally occurring hybrid of '' Semnopithecus johnii'' and '' Semnopithecus dussumieri''. Currently ''S. dussumieri'' is considered a junior synonym of the black-footed gray langur. Distribution This black-footed gray langur is distributed throughout south-western India ( Goa, Karnataka and Kerala Kerala ( ; ) is a state on the Malabar Coast of India. It was formed on 1 November 1956, following the passage of the States Reorganisation Act, by combining Malayalam-speaking regions of the erstwhile regions of ...

Trachypithecus
The lutungs, langurs, or leaf monkeys are a group of Old World monkeys in the genus ''Trachypithecus'' (derived from Greek , meaning "rough" and , meaning "monkey"). Their range is much of Southeast Asia (northeast India, Vietnam, southern China, Borneo, Thailand, Java, and Bali). The name "lutung" comes from the Sundanese language meaning "blackness", ultimately from Proto-Austronesian *''luCuŋ'' (which originally referred to the Formosan rock macaque); it is preferred in one paper because the authors wanted the name langurs to only refer to monkeys in the genus '' Semnopithecus'', although some "lutungs" are now "langurs" again. Evolution Genetic analysis indicates that the ancestors of the modern species of lutung first differentiated from one another a little over 3 million years ago, during the late Pliocene. The various species alive today then diverged during the Pleistocene, presumably driven by habitat changes during the Ice Ages. The oldest fossils clearly ident ...

Nilgiri Langur
The Nilgiri langur (''Semnopithecus johnii'') is a langur (a type of Old World monkey) . This primate has glossy black fur on its body and golden brown fur on its head. It is similar in size and long-tailed like the gray langurs. Females have a white patch of fur on the inner thigh. It typically lives in troops of nine to ten monkeys. Its diet consists of fruits, shoots and leaves. The species is classified as vulnerable due to habitat destruction and poaching for its fur and flesh, the latter believed to have aphrodisiac properties. Taxonomy and Classification The classification of the Nilgiri langur has been disputed. Traditionally it has been placed within the genus ''Trachypithecus'' based on morphological similarities such as cranial morphology and neonatal pelage color, and within the ''Trachypithecus vetulus'' group within ''Trachypithecus'' based on a presumed close relationship with the purple-faced langur, which had been classified as ''Trachypithecus vetulus''.

Old World Monkey
Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae (). Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus ''Papio''), red colobus (genus '' Piliocolobus'') and macaques (genus '' Macaca''). Common names for other Old World monkeys include the talapoin, guenon, colobus, douc (douc langur, genus '' Pygathrix''), vervet, gelada, mangabey (a group of genera), langur, mandrill, surili ('' Presbytis''), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 45 to 55 million years ago. The smallest Old World monkey is the talapoin, with a head and body 34–37 cm in length, and weighing between 0.7 and 1.3 kg. The largest is the male mandrill, around 70 cm in length, and weighing up to 50&nbs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
