Surili
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 ridges, ...

Javan Surili
The Javan surili (''Presbytis comata'') is a vulnerable species of Old World monkey endemic to the western half of Java, Indonesia, a biodiversity hotspot. Other common names by which it is known by include gray, grizzled or Sunda Island surili; grizzled or stripe-crested langur; Javan grizzled langur; grizzled, Java or Javan leaf monkey; langur gris. There are two subspecies of the Javan surili: * ''Presbytis comata comata'' - Occurs in western Java * ''Presbytis comata fredericae'' - Occurs in central Java This colobine species has a sacculated stomach to assist the breakdown in the cellulose from the leaves it feeds on. It has a small, slender face and tail, and large round stomachs. Its coloring ranges from dark gray to white. Leaf monkeys tend to be active during the day, spending up to 5 hours grooming themselves. Distribution The Javan surili is found in the western half of Java, Indonesia. It ranges as far east as Mt. Lawu on the border with East Java. According to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 kg. Old ... [...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 ...

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. Characteristics Colobines are ... [...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. It was formerly considered a subspecies of the Sumatran surili, ''Presbytis melalophos'' (as ''Presbytis melalophos sumatrana'') but genetic analysis revealed that these are separate species. The black Sumatran langur is native to the island of Sumatra in Indonesia. It is listed as endangered by the IUCN due primarily to deforestation Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated d ..., and also due to animals taken for pets.

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 .

Primate
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large bra ...
