Marmoset
The marmosets (), also known as zaris or sagoin, are twenty-two New World monkey species of the genera '' Callithrix'', '' Cebuella'', '' Callibella'', and ''Mico''. All four genera are part of the biological family Callitrichidae. The term "marmoset" is also used in reference to Goeldi's marmoset, ''Callimico goeldii'', which is closely related. Most marmosets are about long. Relative to other monkeys, they show some apparently primitive features; they have claws rather than nails, and tactile hairs on their wrists. They lack wisdom teeth, and their brain layout seems to be relatively primitive. Their body temperature is unusually variable, changing by up to in a day. Marmosets are native to South America and have been found in Bolivia, Brazil, Colombia, Ecuador, Paraguay, and Peru. They have also been occasionally spotted in Central America and southern Mexico. They are sometimes kept as pets, though they have specific dietary and habitat needs that require considerati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cebuella
Pygmy marmosets are two species of small New World monkeys in the genus ''Cebuella''. They are native to Amazon rainforest, rainforests of the western Amazon Basin in South America. These primates are notable for being the smallest monkeys in the world, at just over . They are generally found in evergreen forest, evergreen and riparian forest, river-edge forests and are gum (botany), gum-feeding specialists, or gummivores. About 83% of the pygmy marmoset population lives in stable troops of two to nine individuals, including a dominant male, a breeding female, and up to four successive litters of offspring. The modal size of a standard stable troop would be six individuals. Although most groups consist of family members, some may also include one or two additional adult members. Members of the group communicate using a complex system including vocal, chemical, and visual signals. Three main calling signals depend on the distance the call needs to travel. These monkeys may also ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Marmoset
The common marmoset (''Callithrix jacchus''), also called white-tufted marmoset or white-tufted-ear marmoset, is a New World monkey. It originally lived on the northeastern coast of Brazil, in the states of Piauí, Paraíba, Ceará, Rio Grande do Norte, Pernambuco, Alagoas, and Bahia. Through release (both intentional and unintentional) of captive individuals, it has expanded its range since the 1920s to Southeast Brazil (its first sighting in the wild for Rio de Janeiro was in 1929), where it became an invasive species, raising concerns about genetic pollution of similar species, such as the buffy-tufted marmoset (''Callithrix aurita''), and predation upon bird nestlings and eggs. The whole genome sequence of a female common marmoset was published on 20 July 2014. It became the first New World monkey to have its genome sequenced. Physical description and morphology Common marmosets are very small monkeys with relatively long tails. Males are slightly larger than females; mal ...

Mico (genus)
''Mico'' is a genus of New World monkeys of the family Callitrichidae, the family containing marmosets and tamarins. The genus was formerly considered a subgenus of the genus ''Callithrix''. Taxonomy ''Mico'' differs from ''Callithrix'' in dental morphology, genetics and geographic distribution: ''Callithrix'' species are distributed in eastern Brazil (mainly the Atlantic Forest), while ''Mico'' species are distributed in the Amazon rainforest south of the lower Amazon River, Amazon and Madeira Rivers, though a single species, the black-tailed marmoset, also occurs in the Pantanal and Gran Chaco, Chaco. Roosmalens' dwarf marmoset (''Mico humilis'') was briefly considered to be a member of a new monotypic genus, ''Callibella'', due mainly to differences in size, genetics, and its bearing of a single young rather than the two that marmosets usually bear. Roosmalens' dwarf marmoset is significantly smaller than the ''Mico'' species, being about midway between the typical ''Mico'' sp ...

Callitrichidae
The Callitrichidae (also called Arctopitheci or Hapalidae) are a family of New World monkeys, including marmosets, tamarins, and lion tamarins. At times, this group of animals has been regarded as a subfamily, called the Callitrichinae, of the family Cebidae. This taxon was traditionally thought to be a primitive lineage, from which all the larger-bodied platyrrhines evolved. However, some works argue that callitrichids are actually a dwarfed lineage.Naish, DarrenMarmosets and tamarins: dwarfed monkeys of the South American tropics Scientific American November 27, 2012 Ancestral stem-callitrichids likely were "normal-sized" ceboids that were dwarfed through evolutionary time. This may exemplify a rare example of insular dwarfing in a mainland context, with the "islands" being formed by biogeographic barriers during arid climatic periods when forest distribution became patchy, and/or by the extensive river networks in the Amazon Basin. All callitrichids are arboreal. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callibella
The Roosmalens' dwarf marmoset (''Mico humilis''), also known as the black-crowned dwarf marmoset, is a small New World monkey native to the Amazon Rainforest, on the east bank of the lower Madeira River, and the west bank of the Aripuanã River, in Brazil. It has the smallest distribution of any primate in Amazonia. This marmoset has several unique attributes, which has resulted in it sometimes being placed in the monotypic genus ''Callibella''. However, genetic analysis has subsequently resulted in its being classified within the genus ''Mico''. It was first described in 1998, after it was discovered ca. 400 km (250 mi) south of the city of Manaus. In 1996, Marc van Roosmalen, the discoverer, was given a milk can by a river trader with one of these monkeys inside. He suspected it was a new species, a relative of the pygmy marmoset, but at that point was unaware of its exact origin. Following a lengthy expedition, it was discovered near the town of Nova Olinda in sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goeldi's Marmoset
Goeldi's marmoset, or Goeldi's monkey (''Callimico goeldii''), is a small New World monkey found on the South American continent, mainly in the upper Amazon basin of Bolivia, Brazil, Colombia, and Perú. It is the only species classified in the monotypic genus ''Callimico'', thus these monkeys are sometimes referred to as "callimicos". The species takes its name from its discoverer, Swiss-Brazilian naturalist Emil August Goeldi. Likely an evolutionary adaptation for camouflage and the evasion of predators, Goeldi's marmosets are a dark-furred species, usually a blackish-gray or darker brown in color. Superficially, the short hair on their head gives them a vague resemblance to the larger woolly monkey ('' Lagothrix''); however, the back of their necks, their backside, and tails often display light, horizontal striping or highlights. Their bodies are about long, and their tails are about another long. Captive Goeldi's marmosets weigh around , while observed individuals were appr ...

Callithrix
''Callithrix'' is a genus of New World monkeys of the family Callitrichidae, the family containing marmosets and tamarins. The genus contains the Atlantic Forest marmosets. The name ''Callithrix'' is derived from the Greek words ''kallos'', meaning beautiful, and ''thrix'', meaning hair. Taxonomy The genera ''Mico'' and '' Callibella'' were formerly considered a subgenus of the genus ''Callithrix''. ''Callithrix'' differs from ''Mico'' in dental morphology and geographic distribution; ''Callithrix'' species are distributed near the Atlantic coast of Brazil, while ''Mico'' species are distributed further inland. ''Callithrix'' differs from ''Callibella'' in these features, as well as in size, with ''Callithrix'' species being significantly larger. ''Callithrix'' species differ from the tamarins of the genus ''Saguinus'' in that ''Callithrix'' has enlarged mandibular incisor teeth the same size as the canine teeth, which are used for gouging holes in trees to extract exudate ...

Saguinus
The tamarins are squirrel-sized New World monkeys from the family Callitrichidae in the genus ''Saguinus''. They are the first offshoot in the Callitrichidae tree, and therefore are the sister group of a clade formed by the lion tamarins, Goeldi's monkeys and marmosets. Taxonomy and evolutionary history Hershkovitz (1977) recognised ten species in the genus ''Saguinus'', further divided into 33 morphotypes based on facial pelage. A later classification into two clades was based on variations in dental measurements. A taxonomic review (Rylands et al., 2016) showed the tamarins are a sister group to all other callitrichids, branching off 15–13 million years ago. Within this clade, six species groups are historically recognised, ''nigricollis'', ''mystax'', ''midas'', ''inustus'', ''bicolor'' and ''oedipus'', five of which were shown to be valid with ''Saguinus inustus'' placed within the ''midas'' group. The review noted that the smaller-bodied ''nigricollis'' group began div ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Monkey
Monkey is a common name that may refer to most mammals of the infraorder Simiiformes, also known as simians. Traditionally, all animals in the group now known as simians are counted as monkeys except the apes. Thus monkeys, in that sense, constitute an incomplete paraphyletic grouping; alternatively, if apes (Hominoidea) are included, ''monkeys'' and ''simians'' are synonyms. In 1812, Étienne Geoffroy grouped the apes and the Cercopithecidae group of monkeys together and established the name Catarrhini, "Old World monkeys" ("''singes de l'Ancien Monde''" in French). The extant sister of the Catarrhini in the monkey ("singes") group is the Platyrrhini (New World monkeys). Some nine million years before the divergence between the Cercopithecidae and the apes, the Platyrrhini emerged within "monkeys" by migration to South America likely by ocean. Apes are thus deep in the tree of extant and extinct monkeys, and any of the apes is distinctly closer related to the Cercopith ...

Marc Van Roosmalen
Marc van Roosmalen (born 23 June 1947) is a Dutch-Brazilian primatologist. He was elected as one of the "Heroes for the Planet" by ''Time'' magazine in 2000. His research has led to the identification of several new monkey species, as well as other mammals and plants, although some of these identifications are challenged. He is also an activist in the protection of the Brazilian rainforest. Van Roosmalen was awarded the honour of officer in the Order of the Golden Ark by Prince Bernhard of the Netherlands in 1997. Career Van Roosmalen studied biology at the University of Amsterdam and did four years of doctoral fieldwork beginning in 1976 studying the red-faced spider monkey in Suriname. He later did two more years of work in French Guiana, following which he published the book ''Fruits of the Guianan Flora''. In 1986 he was hired by the INPA (Brazilian National Institute of Amazonian Research, where he initially thrived. During this period, he launched a non-governmental ...
