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 ''Sanguinus inustus'' placed within the ''midas'' group. The review noted that the smaller-bodied ''nigricollis'' group began diver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saguinus Oedipus
The cotton-top tamarin (''Saguinus oedipus'') is a small New World monkey weighing less than . This New World monkey can live up to 24 years, but most of them die by 13 years. One of the smallest primates, the cotton-top tamarin is easily recognized by the long, white sagittal crest extending from its forehead to its shoulders. The species is found in tropical forest edges and secondary forests in northwestern Colombia, where it is arboreal and diurnal. Its diet includes insects and plant exudates, and it is an important seed disperser in the tropical ecosystem. The cotton-top tamarin displays a wide variety of social behaviors. In particular, groups form a clear dominance hierarchy where only dominant pairs breed. The female normally gives birth to twins and uses pheromones to prevent other females in the group from breeding. These tamarins have been extensively studied for their high level of cooperative care, as well as altruistic and spiteful behaviors. Communication betwe ...

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] |
Emperor Tamarin
The emperor tamarin (''Saguinus imperator'') is a species of tamarin allegedly named for its resemblance to the German Empire, German List_of_German_monarchs#German_Empire,_1871–1918, emperor Wilhelm II, German Emperor, Wilhelm II. It lives in the west Brazilian States of Brazil, states of Acre State, Acre and Amazonas State, Brazil, Amazonas and the southwest Amazon Basin, in east Peru, north Bolivia. The fur of the emperor tamarin is predominantly grey colored, with yellowish speckles on its chest. The hands and feet are black and the tail is brown. Outstanding is its long, white beard, which extends to both sides beyond the shoulders. The animal reaches a length of , plus a long tail. It weighs approximately . Physical description (''Saguinus imperator imperator'') Black-chinned emperor tamarin There are claws on each of the animal's toes and fingers, aside from its big toe which has a nail. While it has a definitive long mustache, it also has almost inconspicuous white h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saguinus Geoffroyi
Geoffroy's tamarin (''Saguinus geoffroyi''), also known as the Panamanian, red-crested or rufous-naped tamarin, is a tamarin, a type of small monkey, found in Panama and Colombia. It is predominantly black and white, with a reddish nape. Diurnal, Geoffroy's tamarin spends most of its time in trees, but does come down to the ground occasionally. It lives in groups that most often number between three and five individuals, and generally include one or more adults of each sex. It eats a variety of foods, including insects, exudates, fruits and other plant parts. Insects and fruits account for the majority of its diet, but exudates are also important. But since its teeth are not adapted for gouging trees to get to the sap, it can only eat exudates when they are easily available. Although a variety of reproductive methods are used, the most common is for a single adult female in the group to be reproductively active and to mate with multiple adult males in the group.

Moustached Tamarin
The moustached tamarin (''Saguinus mystax'') is a New World monkey and a species of tamarin. The moustached tamarin is named for the lack of coloring in the facial hair surrounding their mouth, appearing similar to a moustache. As with all New World monkeys, the moustached tamarin is found only in areas of Central and South America. Taxonomy There are 3 subspecies of the moustached tamarin: * Spix's moustached tamarin, ''Saguinus mystax mystax'' * White-rumped moustached tamarin, ''Saguinus mystax pluto'' * Red-capped tamarin, ''Saguinus mystax pileatus'' Description Moustached tamarins have a lifespan of about 20 years. They are small, weighing 500 to 600 grams, and range in length from 30 to 92 centimeters, with adult females larger than males. Moustached tamarin monkeys are characterized by white, curly hair around their mouth, similar to a moustache. Their face is flat with almond-like shaped eyes. Their ears are furry and large, and they have long, silky, body hair. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Tamarin
The black tamarin (''Saguinus niger'') or western black-handed tamarin, is a species of tamarin endemic to Brazil. Taxonomy Based on mitochondrial DNA analysis, black tamarins were found to be more closely related to populations on the same side of the Tocantins River than on the other, showing that the river constitutes an effective gene flow barrier. As a consequence of the genetic divergence, as well as minor differences in pelage color, some recent authorities have argued for recognizing the population east of the Tocantins River as '' S. ursulus'' (eastern black-handed tamarin), leaving the "true" ''S. niger'' for the population west of this river. The closest living relative of the black tamarin is thought to be the golden-handed tamarin (''S. midas''). Description Black-handed tamarins are among the smallest primates, weighing approximately 500 grams. As with other tamarins, the hind limbs are longer than the forelimbs and the thumbs are not opposable. With the exception ...

Saguinus Midas
The golden-handed tamarin (''Saguinus midas''), also known as the red-handed tamarin or Midas tamarin, is a New World monkey belonging to the family Callitrichidae. Distribution and habitat This species is native to wooded areas north of the Amazon River in Brazil, Guyana, French Guiana, Suriname, and possibly Venezuela. A population of tamarins south of the Amazon River that lack the contrasting feet and hands was previously believed to be a sub-population of golden-handed tamarins but is now treated as a separate species, the black tamarin. Populations of golden-handed tamarins appear to be expanding into the historical range of the pied tamarin, with the golden-handed tamarin gradually displacing the pied tamarin through interspecific competition. This species prefers trees with small crowns. Description The golden-handed tamarin's body measures ; including the tail it measures . It weighs . The fur of the golden-handed tamarin is dark brown or black, with contrasting gold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saguinus Bicolor
The pied tamarin (''Saguinus bicolor''), sometimes referred to as the Brazilian bare-faced tamarin, is a Critically Endangered primate species found in a restricted area of the Brazilian Amazon Rainforest. It was named the mascot of Manaus, Brazil in 2005. The species is endangered due to the increasing size of the city of Manaus which is encroaching on their native habitat. Distribution and habitat A New World monkey, it is found at the city limits of Manaus, the capital of the Amazonas state of Brazil and up to 35 km to the north and 100 km to the east. The main distribution is in the rio Cuieiras and rio Preto da Eva interfluvium. Pied tamarins are also found in the adjacent rio Preto da Eva and rio Urubu interfluvium, but are comparatively rare. There appears to be interspecific competition between the pied tamarin and the red-handed tamarin with the red-handed tamarin gradually displacing the pied tamarin from areas of its historical distribution.
