Cebuella
Pygmy marmosets are two species of small New World monkeys in the genus ''Cebuella''. They are native to 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 and river-edge forests and are 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 make visual displays when threatened or to show dominance. Chemical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western Pygmy Marmoset
The western pygmy marmoset (''Cebuella pygmaea'') is a marmoset species, a very small New World monkey found in the northwestern Amazon rainforest in Brazil, Colombia, Ecuador, and Peru. It was formerly regarded as conspecific with the similar eastern pygmy marmoset, which has whitish underparts. Although the western pygmy marmoset occurs further west than the eastern pygmy marmoset, the primary separators of their ranges are the Amazon River (Solimões River) and Marañón River, with the western occurring to the north of them and the eastern to the south. Physical Description The western pygmy marmoset is the worlds smallest monkey. Pygmy marmosets have only a slight degree of sexual dimorphism; in the wild the average male weighs , which is slightly smaller than the average female at . Fully grown western pygmy marmosets have an average body length of , and a tail marked with black rings that is on average longer than their bodies at . They have fluffy "brownish-gold fur ...

Cebuella Niveiventris
The eastern pygmy marmoset (''Cebuella niveiventris'') is a marmoset species, a very small New World monkey, found in the southwestern Amazon Rainforest in Bolivia, Brazil, Ecuador, and Peru. It was formerly regarded as conspecific with the similar western pygmy marmoset, but the eastern pygmy marmoset has whitish colored underparts. Although the eastern pygmy marmoset occurs further east than the western pygmy marmoset, the primary separators of their ranges are the Amazon River (Solimões River) and Maranon River, with the western occurring to the north of them and the eastern to the south. The species has recently been confirmed by DNA testing to exist in Ecuador, hundreds of kilometers north of the Maranon River. Physical Description The eastern pygmy marmoset weighs around 119 grams and have a head size ranging from 33.7 to 38.9mm, being one of the smallest New World monkeys. In the wild, full grown adult males weigh approximately 110 grams whereas adult females can weigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marmoset
The marmosets (), also known as zaris or sagoin, are 22 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 4°C (7°F) 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 consideration. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 exudates. ...

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 south of Rio Madeira, though a single species, the black-tailed marmoset, also occurs in the Pantanal and 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'' species and the pygmy marmoset, ''Cebuella pygmaea''. ''Mico' ...

Arboreal
Arboreal locomotion is the Animal locomotion, locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.Cartmill, M. (1985). Climbing. In ''Functional Vertebrate Morphology'', eds. M. Hildebrand D. M. Bramble K. F. Liem and D. B. Wake, pp. 73–88. Cambridge: Belknap Press. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as the tree snail. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in diverse ways. These challenges include moving on n ...

Dentition
Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiology (that is, the relationship between the shape and form of the tooth in question and its inferred function) of the teeth of an animal. Animals whose teeth are all of the same type, such as most non-mammalian vertebrates, are said to have '' homodont'' dentition, whereas those whose teeth differ morphologically are said to have '' heterodont'' dentition. The dentition of animals with two successions of teeth (deciduous, permanent) is referred to as ''diphyodont'', while the dentition of animals with only one set of teeth throughout life is ''monophyodont''. The dentition of animals in which the teeth are continuously discarded and replaced throughout life is termed ''polyphyodont''. The dentition of animals in which the teeth are set in so ...
