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] |
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 Piaui, Paraiba, 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, 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 and females are of s ...

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' ...

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] |
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 southeas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callimico
The Goeldi's marmoset or Goeldi's monkey (''Callimico goeldii'') is a small, South American New World monkey that lives in the upper Amazon basin region of Bolivia, Brazil, Colombia, and Peru. It is the only species classified in the genus ''Callimico'', and the monkeys are sometimes referred to as "callimicos". The species takes its name from its discoverer, Swiss-Brazilian naturalist Emil August Goeldi. Goeldi's marmosets are blackish or blackish-brown in color and the hair on their head and tail sometimes has red, white, or silverly brown highlights. Their bodies are about long, and their tails are about long. They weigh about 0.4835 Kg in captivity and 0.500 Kg in the wild. Their digits have claw like nails except for the hallux, which serve for clinging, scansorial travel, and to extract food from trees. Taxonomy and Evolution Goeldi's marmoset was first described in 1904, making ''Callimico'' one of the more recent monkey genera to be described. In older classification ...

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. ...

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] |

Brain
A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 14–16 billion neurons, and the estimated number of neurons in the cerebellum is 55–70 billion. Each neuron is connected by synapses to several thousand other neurons. These neurons typically communicate with one another by means of long fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells. Physiologically, brains exert centralized control over a body's other organs. They act on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated respon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
