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 .
The cotton-top tamarin (Saguinus oedipus) is a small New World monkey weighing less than 0.5 kg (1.1 lb). 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.

Platyrrhini is one of three clades that form the suborder Haplorrhini, itself one of two suborders in the order Primates. They are ...
A survey conducted in 1992 found the number of wild population of golden lion tamarins to be 562 individuals in 109 groups. Currently, the average group size includes 3.6 to 5.7 individuals and densities from 0.39 groups/km to 2.35 groups/km. [ 34 ] These predatory attacks occur at the golden lion tamarin sleeping sites.
The brown-mantled tamarin (Leontocebus fuscicollis), also known as Spix's saddle-back tamarin, is a species of saddle-back tamarin. This New World monkey is found in the Southern American countries of Bolivia , Brazil and Peru .
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.
Emperor tamarins behave actively, rapidly, gracefully, gregariously, and playfully in the wild. In captivity the tamarins are very social and interactive with humans. A study by Knox, Kerry L. and Donald Stone Sade of the social behavior of emperor tamarins in captivity found that tamarin colonies behave agonistically according to seniority.
Proyecto Tití's programs combine field research, education and community programs. The cotton-top tamarin, is one of the most endangered primates in the world and is found only in North-Western Colombia. [3]
