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.Hershkovitz, P. Living New World Monkeys (Platyrrhini) with an Introduction to the Primates.
University of Chicago 1977.
However, some works argue that callitrichids are actually a dwarfed lineage.Naish, Darren.

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 the smallest of the simian primates.
They eat insects, fruit, and the sap or gum from trees; occasionally, they take small vertebrates.
The marmosets rely quite heavily on tree exudates, with some species (e.g. Callithrix jacchus and Cebuella pygmaea) considered obligate exudativores.
Callitrichids typically live in small, territorial groups of about five or six animals.
Their social organization is unique among primates, and is called a "cooperative polyandrous group".
This communal breeding system involves groups of multiple males and females, but only one female is reproductively active.
Females mate with more than one male and each shares the responsibility of carrying the offspring.
They are the only primate group that regularly produces twins, which constitute over 80% of births in species that have been studied.
Unlike other male primates, male callitrichids generally provide as much parental care as females.
Parental duties may include carrying, protecting, feeding, comforting, and even engaging in play behavior with offspring.
In some cases, such as in the cotton-top tamarin (Saguinus oedipus), males, particularly those that are paternal, even show a greater involvement in caregiving than females.Cleveland and Snowdon.

432-444 The typical social structure seems to constitute a breeding group, with several of their previous offspring living in the group and providing significant help in rearing the young.
