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 States and union territories of India, 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 r ...

Edward Blyth
Edward Blyth (23 December 1810 – 27 December 1873) was an English zoologist who worked for most of his life in India as a curator of zoology at the Asiatic Society, Royal Asiatic Society of Bengal in Calcutta. He set about updating the museum's catalogues, publishing a ''Catalogue of the Birds of the Asiatic Society'' in 1849. He was prevented from doing much fieldwork himself, but received and described bird specimens from Allan Octavian Hume, A.O. Hume, Samuel Tickell, Robert Swinhoe among others. His ''Natural History of the Cranes'' was published posthumously in 1881. Early life and work On 23 December 1810, Blyth was born in London. His father, a cloth merchant, clothier, died in 1820 and his mother sent him to Dr. Fennell's school in Wimbledon, London, Wimbledon. He took an interest in reading, but was often to be found spending time in the woods nearby. Leaving school in 1825, he went to study chemistry, at the suggestion of Dr. Fennell, in London under Dr. Keating at S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old World Monkey
Old World monkeys are primates in the family 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, drill, surili ('' Presbytis''), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys, with the Old World monkeys and apes diverging from a common ancestor between 25 million and 30 million years ago. This clade, containing the Old World monkeys and the apes, diverged from a common ancestor with the New World monkeys around 45 to 55 million years ago. The individual species of Old World monkey are more closely related to each other than to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Langur
The Colobinae or leaf-eating monkeys are a subfamily of the Old World monkey family that includes 61 species in 11 genera, including the black-and-white colobus, the large-nosed proboscis monkey, and the gray langurs. Some classifications split the colobine monkeys into two tribes, while others split them into three groups. Both classifications put the three African genera '' Colobus'', '' Piliocolobus'', and '' Procolobus'' in one group; these genera are distinct in that they have stub thumbs (Greek κολοβός ''kolobós'' = "docked"). The various Asian genera are placed into another one or two groups. Analysis of mtDNA confirms the Asian species form two distinct groups, one of langurs and the other of the "odd-nosed" species, but are inconsistent as to the relationships of the gray langurs; some studies suggest that the gray langurs are not closely related to either of these groups, while others place them firmly within the langur group.

Gray Langur
''Semnopithecus'' is a genus of Old World monkeys native to the Indian subcontinent, with all species with the exception of two being commonly known as gray langurs. Traditionally only the 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. Members of the genus ''Semnopithecus'' are 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 d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf-eating
In zoology, a folivore is a herbivore that specializes in eating leaves. Mature leaves contain a high proportion of hard-to-digest cellulose, less energy than other types of foods, and often toxic compounds.Jones, S., Martin, R., & Pilbeam, D. (1994) ''The Cambridge Encyclopedia of Human Evolution''. Cambridge: Cambridge University Press For this reason, folivorous animals tend to have long digestive tracts and slow metabolisms. Many enlist the help of symbiotic bacteria to release the nutrients in their diet. Additionally, as has been observed in folivorous primates, they exhibit a strong preference for immature leaves which tend to be easier to masticate, are higher in energy and protein, and lower in fibre and poisons than more mature fibrous leaves. Folivory and flight It has been observed that folivory is extremely rare among flying vertebrates. Morton (1978) attributed this to the fact that leaves are heavy, slow to digest, and contain little energy relative to other foo ...

Semnopithecus Entellus
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''. Description The fur of adults is mostly light colored, with darker fur on the back and limbs, and the face, ears, hands and feet are all black. Infants are brown. Body size excluding tail ranges from to long, and the tail length is between and . Adult males weigh between and while adult females weigh between ...

Semnopithecus Dussumieri
Southern plains gray langur was the common name ascribed to ''Semnopithecus dussumieri'' by ''Mammal Species of the World'' (3rd edition) in 2005. Along with several other ''Semnopithecus'', it had been previously considered a subspecies of the northern plains gray langur, ''Semnopithecus entellus'', i.e., ''Semnopithecus entellus dussumieri''. Subsequent genetic research has revealed that ''Semnopithecus dussumieri'' is an invalid taxon. These monkeys live in groups in forests and other rural habitats, with some groups being habituated to human contact and feeding. They are herbivorous, feeding by day mainly on foliage, fruits and flowers, and sleeping at night high in a tree. Taxonomy The taxonomy of gray langurs has been in a state of flux. At first, all gray langurs were included in a single species, ''Semnopithecus entellus'', with several subspecies, but more recently some authorities have elevated these to species status. The southern plains gray langur was the common nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semnopithecus Johnii
The Nilgiri langur (''Semnopithecus johnii'') is an Asian langur of the Old World monkey. It has glossy, black fur and an orangey-golden brown, hair-like mane on its head. Females have a white patch of fur on the inner thigh. It typically lives in troops of nine to ten individuals, with or without offspring, depending on seasonality. Its diet consists of fruits, shoots and leaves. It is listed as vulnerable on the IUCN Red List and is threatened by habitat destruction and poaching for its body parts, thought to supposedly contain 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 (''Semnopithecus vetulus''), which had fo ...
