The Callitrichidae 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.
Goeldi's marmoset, or Goeldi's monkey, 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.
A genetic chimerism or chimera is a single organism composed of cells with more than one distinct genotype. Animal chimeras can be produced by the merger of two embryos. In plants and some animal chimeras, mosaicism involves distinct types of tissue that originated from the same zygote but differ due to mutation during ordinary cell division.
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 100 g (3.5 oz). They are generally found in evergreen and river-edge forests and are gum-feeding specialists, or gummivores.
Wied's marmoset, also known as Wied's black-tufted-ear marmoset, is a New World monkey that lives in tropical and subtropical forests of eastern Brazil. Unlike other marmosets, Wied's marmoset lives in groups consisting of 4 or 5 females and 2 or 3 males. They are matriarchal, and only the dominant female is allowed to mate. Like other marmosets, the offspring are always born in pairs.
The silvery marmoset is a New World monkey that lives in the eastern Amazon Rainforest in Brazil.
The buffy-tufted marmoset, also known as the buffy tufted-ear marmoset or white-eared marmoset, is a New World monkey that lives in the forests on the Atlantic coast of southeast Brazil. Of all the marmosets, it has the southernmost range.
The common marmoset, 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 of captive individuals, it has expanded its range since the 1920s to Southeast Brazil, where it became an invasive species, raising concerns about genetic pollution of similar species, such as the buffy-tufted marmoset, and predation upon bird nestlings and eggs.
The black-tufted marmoset is a species of New World monkey that lives primarily in the Neotropical gallery forests of the Brazilian Central Plateau. It ranges from Bahia to Paraná, and as far inland as Goiás, between 14°S and 25°S, and can commonly be seen in the Rio de Janeiro city where it was introduced. This marmoset typically resides in rainforests, living an arboreal life high in the trees, below the canopy. They are only rarely spotted near the ground.
The Roosmalens' dwarf marmoset, 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.
The buffy-headed marmoset is a rare species of marmoset endemic to the rainforests of south-eastern Brazil. It occurs in southern Espírito Santo and possibly northern Rio de Janeiro and its distribution extends into Minas Gerais.
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.
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.
A gummivore is an omnivorous animal whose diet consists primarily of the gums and saps of trees and bugs for protein. Notable gummivores include arboreal, terrestrial primates like certain marmosets and lemurs. These animals that live off of the injuries of trees live from about 8m off of the ground up to the canopies. The feeding habit of gummivores is gummivory.
Lagonimico is an extinct genus of New World monkeys from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is Lagonimico conclucatus.
Micodon is an extinct genus of New World monkeys from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is M. kiotensis, a very small monkey among the New World species.
The western pygmy marmoset 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 and Marañón River, with the western occurring to the north of them and the eastern to the south.
The eastern pygmy marmoset 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 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.
Schneider's marmoset is a species of marmoset of the genus Mico in the family Callitrichidae. Endemic to Brazil, it is found in the Amazon rainforest of Mato Grosso state. It is found on the interfluve between the Juruena and Teles Pires rivers. Schneider's marmoset is found in primary and secondary terra firma rainforests and in the transition zone to the Cerrado.
