Old World Monkeys
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] |
Olive Baboon
The olive baboon (''Papio anubis''), also called the Anubis baboon, is a member of the family Cercopithecidae Old World monkeys. The species is the most wide-ranging of all baboons, being native to 25 countries throughout Africa, extending from Mali eastward to Ethiopia and Tanzania. Isolated populations are also present in some mountainous regions of the Sahara. It inhabits savannahs, steppes, and forests. The common name is derived from its coat colour, which is a shade of green-grey at a distance. A variety of communications, vocal and non-vocal, facilitate a complex social structure. Characteristics The olive baboon is named for its coat, which, at a distance, is a shade of green-grey. At closer range, its coat is multicoloured, due to rings of yellow-brown and black on the hairs. The hair on the baboon's face is coarser and ranges from dark grey to black. This coloration is shared by both sexes, although males have a mane of longer hair that tapers down to ordinary length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guenon
The guenons (, ) are Old World monkeys of the genus ''Cercopithecus'' (). Not all members of this genus have the word "guenon" in their common names; also, because of changes in scientific classification, some monkeys in other genera may have common names that include the word "guenon". Nonetheless, the use of the term guenon for monkeys of this genus is widely accepted. All members of the genus are endemic to sub-Saharan Africa, and most are forest monkeys. Many of the species are quite local in their ranges, and some have even more local subspecies. Many are threatened or endangered because of habitat loss. The species currently placed in the genus ''Chlorocebus'', such as vervet monkeys and green monkeys, were formerly considered as a single species in this genus, ''Cercopithecus aethiops''. In the English language, the word "guenon" is apparently of French origin. In French, ''guenon'' was the common name for all species and individuals, both males and females, from the gen ...

New World Monkey
New World monkeys are the five families of primates that are found in the tropical regions of Mexico, Central and South America: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae. The five families are ranked together as the Ceboidea (), the only extant superfamily in the parvorder Platyrrhini (). Platyrrhini is derived from the Greek for "broad nosed", and their noses are flatter than those of other simians, with sideways-facing nostrils. Monkeys in the family Atelidae, such as the spider monkey, are the only primates to have prehensile tails. New World monkeys' closest relatives are the other simians, the Catarrhini ("down-nosed"), comprising Old World monkeys and apes. New World monkeys descend from African simians that colonized South America, a line that split off about 40 million years ago. Evolutionary history About 40 million years ago, the Simiiformes infraorder split into the parvorders Platyrrhini (New World monkeys) and Catarrhini (apes and Old World mon ...

Proboscis Monkey
The proboscis monkey (''Nasalis larvatus'') or long-nosed monkey is an arboreal Old World monkey with an unusually large nose, a reddish-brown skin color and a long tail. It is endemic to the southeast Asian island of Borneo and is found mostly in mangrove forests and on the coastal areas of the island. This species co-exists with the Bornean orangutan and monkeys such as the silvery lutung. It belongs in the monotypic genus ''Nasalis''. Taxonomy and names Proboscis monkeys belong to the subfamily Colobinae of the Old World monkeys. The two subspecies are: *''N. l. larvatus'' (Wurmb, 1787), which occupies the whole range of the species *''N. l. orientalis'' (Chasen, 1940), restricted to north-east Kalimantan However, the difference between the subspecies is small, and not all authorities recognise ''N. l. orientalis''. The species is known as ''monyet belanda'' in Malaysia or ''bekantan'' in Indonesia. Description The proboscis monkey is a large species, being one of the lar ...

Patas
The common patas monkey (''Erythrocebus patas''), also known as the wadi monkey or hussar monkey, is a ground-dwelling monkey distributed over semi-arid areas of West Africa, and into East Africa. Taxonomy There is some confusion surrounding if there are valid subspecies, with some listing four, others three, and others listing two: the western ''Erythrocebus patas patas'' (with a black nose) and the eastern ''E. patas pyrrhonotus'' (with a white nose). However, it was later discovered that the nose colour used to separate these subspecies could change to white during pregnancy in females, as well as in general as animals aged, and ''E. patas pyrrhonotus'' in Kenya often did not have white noses, thus ''Mammal Species of the World'' has classified ''E. patas'' as a monotypic species. The genus status of the species has previously been in flux. Colin Groves first argued the species was closely related to ''Cercopithecus aethiops'' in 1989, based on anatomical morphology. Phylo ...

Presbytis
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, a ...

Mandrill
The mandrill (''Mandrillus sphinx'') is a large Old World monkey native to west central Africa. It is one of the most colorful mammals in the world, with red and blue skin on its face and posterior. The species is sexually dimorphic, as males have a larger body, longer canine teeth and brighter coloring. Its closest living relative is the drill with which it shares the genus ''Mandrillus''. Both species were traditionally thought to be baboons, but further evidence has shown that they are more closely related to white-eyelid mangabeys. Mandrills mainly live in tropical rainforests but will also travel across savannas. They are active during the day and spend most of their time on the ground. Their preferred foods are fruit and seeds, but mandrills will consume leaves, piths, mushrooms, and animals from insects to juvenile antelope. Mandrills live in large, stable groups known as "hordes" which can number in the hundreds. Females form the core of these groups, while adult mal ...

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] |
Mangabey
Mangabeys are West-African Old World monkeys, with species in three of the six genera of tribe Papionini. The more typical representatives of ''Cercocebus'', also known as the white-eyelid mangabeys, are characterized by their bare, upper eye-lids which are lighter than their facial skin colouring, and the uniformly coloured hairs of the fur. Members of ''Lophocebus'', the crested mangabeys, tend to have dark skin, eyelids that match their facial skin, and crests of hair on their heads. A new species, the highland mangabey, was discovered in 2003 and was initially placed in ''Lophocebus''. The genus ''Rungwecebus'' was later created for this species. ''Lophocebus'' and ''Cercocebus'' were once thought to be very closely related, so much so that all the species were in one genus. However, the species within genus ''Lophocebus'' are now thought to be more closely related to the baboons in genus '' Papio'', while the species within genus ''Cercocebus'' are more closely related to ...

Gelada
The gelada (''Theropithecus gelada'', am, ጭላዳ, translit=č̣əlada), sometimes called the bleeding-heart monkey or the gelada baboon, is a species of Old World monkey found only in the Ethiopian Highlands, living at elevations of above sea level. It is the only living member of the genus ''Theropithecus'', a name derived from the Greek root words for "beast-ape". Like its close relatives in genus ''Papio'', the baboons, it is largely terrestrial, spending much of its time foraging in grasslands, with grasses comprising up to 90% of its diet. It has buff to dark brown hair with a dark face and pale eyelids. Adult males have longer hair on their backs and a conspicuous bright red patch of skin shaped like an hourglass on their chests. Females also have a bare patch of skin but it is less pronounced, except during estrus, when it brightens and exhibits a "necklace" of fluid-filled blisters. Males average and females average in weight. The head-body length is with a tail of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vervet
The vervet monkey (''Chlorocebus pygerythrus''), or simply vervet, is an Old World monkey of the family Cercopithecidae native to Africa. The term "vervet" is also used to refer to all the members of the genus ''Chlorocebus''. The five distinct subspecies can be found mostly throughout Southern Africa, as well as some of the eastern countries. Vervets were introduced to Florida, St. Kitts and Nevis, Barbados, and Cape Verde. These mostly herbivorous monkeys have black faces and grey body hair color, ranging in body length from about for females, to about for males. In addition to behavioral research on natural populations, vervet monkeys serve as a nonhuman primate model for understanding genetic and social behaviors of humans. They have been noted for having human-like characteristics, such as hypertension, anxiety, and social and dependent alcohol use. Vervets live in social groups ranging from 10 to 70 individuals, with males moving to other groups at the time of sexual mat ...
