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 .
In Spanish, it is commonly called bichichi, tití pielroja, tití blanco, tití cabeza blanca, or tití leoncito. [2] [5] In German-speaking areas, the cotton-top tamarin is commonly known as Lisztaffe (literally "Liszt monkey") due to the resemblance of its crest to the hairstyle of Hungarian composer and piano virtuoso Franz Liszt.

Like the other tamarins and marmosets, Geoffroy's tamarin is a New World monkey classified within the family Callitrichidae. [2] In 2001, Colin Groves included the Callitrichids in the family Cebidae, which also includes capuchin monkeys and squirrel monkeys, but in 2009 Anthony Rylands and Russell Mittermeier reverted to older classifications which considered Callitrichidae a separate family.
By late afternoon, they move to their night dens. Tamarin groups use hollow tree cavities, dense vines or epiphytes as sleeping sites. Sites that are between 11 and 15 m (36 and 49 ft) off the ground are preferred. The golden lion tamarin tends to be active earlier and retire later in the warmer, wetter times of the year as the days are longer ...
The white-lipped tamarin (Saguinus labiatus), also known as the red-bellied tamarin, is a tamarin which lives in the Amazon area of Brazil and Bolivia. The red belly of these New World monkeys is its most remarkable outward characteristic. Otherwise it is black with a thin white mustache on its face and a black-brown back.
Based on mitochondrial DNA analysis, Saguinus niger, the black-handed tamarin, was split into two species: S. niger, the western black-handed tamarin, and S. ursulus, the eastern black-handed tamarin. The Tocantins River which divided the range was found to constitute an effective gene flow barrier.
The black-handed tamarin is classified as Vulnerable by the IUCN as a result of a 30% decrease in population size over the last 18 years, and is likely to become endangered if conservation measures are not taken. Because the major threat to the species appears to be a loss of suitable habitat, habitat conservation is thought to be key in their ...
The golden-mantled tamarin is an arboreal, diurnal species ranging through the understory, moving by quadrupedal walk and leap, mainly on small horizontal supports. Leaping is the main gap-crossing mode of locomotion, though it decreases in proportion with a higher use of the upper forest layers. [8]
