Presbytis Cristatus
The surilis are a group of Old World monkeys in the genus ''Presbytis''. They live in the Thai-Malay Peninsula, on Sumatra, Borneo, Java and smaller nearby islands. Besides surili, the common names for the monkeys in the genus also sometimes use the terms "langur" or "leaf monkey." Description Surilis are rather small, slimly built primates. Their fur at the top is brown, grey, black, or orange, and at the lower surface whitish or greyish, sometimes also orange, with some species having fur designs at the head or at the hips.Novak, R. M. (1999). ''Walker's Mammals of the World.'' 6th edition. Johns Hopkins University Press, Baltimore. Rowe, N. (1996). ''The Pictorial Guide to the Living Primates.'' Pogonias Press, Rhode Island. Their German name of ''Mützenlanguren'' ("capped langurs") comes from the hair on their head, which forms a tuft. They differ from the other langurs by characteristics in the shape of their head (particularly the poorly developed or absent brow r ...

Lawu on the border with East Java. According to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mentawai Langur
The Mentawai langur (''Presbytis potenziani'') is a species of primate in the family Cercopithecidae. It is endemic to the Mentawai Islands in Indonesia. Its natural habitat is subtropical or tropical dry forests. The Siberut langur (''P. siberu'') was formerly considered a subspecies of the Mentawai langur. Description Mentawai langur infants are born with a white pelage. After two to three weeks, the pelage begins to darken and the face becomes darkly pigmented. This change of coloration begins in the dorsal midline and head and ends laterally. After three months, the belly and chest are dark reddish-brown, throat, cheeks, forehead and tip of tail are white and the rest of the body is jet black. Males are differentiated from females by having a white circumgenital patch of fur. Mentawai langurs have a slender body with hind limbs longer than their forelimbs. Distribution and habitat Mentawai langurs are endemic to the islands of Sipora, North Pagai, and South Pagai. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Sumatran Langur
The black Sumatran langur (''Presbytis sumatrana'') is a species of monkey in the family Cercopithecidae.

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

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 wherea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 identif ...

Miller's Grizzled Langur
Miller's langur (''Presbytis canicrus''), also known as Miller's grizzled langur or Kutai grey langur, is a species of leaf monkey. It is endemic to East Kalimantan on the island of Borneo in Indonesia. It is one of the world's most endangered primates, and was at one time thought to be extinct, until it was rediscovered in 2012. Taxonomy Miller's langur is a leaf monkey within the family Cercopithecidae and subfamily Colobinae. It was formerly considered a subspecies of Hose's langur, ''Presbytis hosei'' (as ''Presbytis hosei canicrus''). It was split from ''P. hosei'' on the basis of different morphology by primatologists Colin Groves and Christian Roos. Distribution and habitat Miller's langur is native to the island of Borneo in the province of East Kalimantan in Indonesia. It lives in dipterocarp rainforests up to an elevation of about . Description Miller's langur ranges from to long excluding tail and has a tail length ranging from to . Males weigh from to while ...

Sarawak Surili
The Sarawak surili (''Presbytis chrysomelas'') is a species of primate in the family Cercopithecidae. It is endemic to the southeast Asian island of Borneo, where it is distributed north of the Kapuas River in Kalimantan, Indonesia, the Malaysia states of Sarawak and Sabah, and in Brunei. Its taxonomy is complex and disputed,Brandon-Jones, D., Eudey, A. A., Geissmann, T., Groves, C. P., Melnick, D. J., Morales, J. C., Shekelle, M. and Stewart, C.-B. 2004. ''Asian primate classification.'' International Journal of Primatology 25(1): 97-164. and it has been considered a subspecies of '' P. femoralis'' or '' P. melalophos''. The Sarawak surili was formerly considered common, but has declined drastically due to persecution and habitat loss, and as of 2008 is only known from five sites with a combined population of 200–500 individuals. Consequently, it is believed to be one of the rarest primates in the world, and has been rated as critically endangered by IUCN. References Sara ...
