Tamarin Monkeys: A Complete Species Guide
Tamarins (genus Saguinus, Leontopithecus, and related genera) are small New World monkeys closely related to marmosets, native to Central and South America. They are known for distinctive facial hair and, in the golden lion tamarin, striking coloration. This guide covers tamarin biology, needs, and legal considerations.

About Tamarin Monkeys
Tamarins are small, active New World monkeys in the same family as marmosets, often distinguished by facial hair tufts, mustaches, or manes depending on species. Like marmosets, tamarins typically give birth to twins and rely on cooperative family care.
Physical Characteristics
Tamarins have claws rather than nails on most digits, a long non-prehensile tail, and often striking facial or head fur features, from the golden lion tamarin’s dramatic mane to the emperor tamarin’s long white mustache.
Habitat and Natural Range
Tamarins are found from Central America through much of South America, occupying tropical rainforest, secondary growth, and forest edge habitats depending on species.
Diet
Tamarins are omnivorous, eating fruit, insects, and small vertebrates, with some species also feeding on tree exudates similarly to marmosets, though generally to a lesser extent. See our general primate diet guide for related background.
Behavior and Social Structure
Tamarins live in small cooperative family groups, often with multiple adults assisting in carrying and caring for twin infants. They are vocal and use scent marking extensively to communicate within and between groups.
Care and Welfare Considerations
Tamarins are active, social animals requiring companionship, varied enrichment, and careful dietary management to support their high metabolic needs. Prospective caregivers should research species-specific requirements thoroughly given the diversity within this group.
Legal and Regulatory Considerations
Tamarin ownership, sale, and transport regulations vary by country, state, county, and municipality, and some species’ threatened status may add permit requirements. We do not claim ownership is legal everywhere. Review our primate ownership law overview and confirm current requirements with your local wildlife authority.
Conservation
Conservation status varies considerably across tamarin species; the golden lion tamarin, for example, has been the focus of a notable conservation recovery effort after nearing extinction, while other species remain more secure.
Frequently Asked Questions
What is the difference between a tamarin and a marmoset?
Tamarins generally lack the specialized gum-feeding incisors of marmosets and rely more on fruit and insects, though both belong to the same family; see our Marmoset Monkeys category for comparison.
How big do tamarins get?
Adult tamarins typically weigh between 0.75 and 1.5 pounds depending on species.
Do tamarins have twins?
Yes, like marmosets, tamarins commonly give birth to twins, with multiple family members assisting in their care.
What do tamarins eat?
Tamarins eat a diet of fruit, insects, and small vertebrates, with some species also consuming tree exudates.
Is it legal to own a tamarin?
Legality varies by jurisdiction and species’ conservation status may affect permit requirements in some areas. Always confirm current regulations locally.
Are tamarins endangered?
Conservation status varies widely by species, from Least Concern to Critically Endangered, such as certain lion tamarin populations.
How long do tamarins live?
Tamarins typically live 10 to 18 years depending on species and care conditions.
How social are tamarins?
Tamarins are highly social, living in small cooperative family groups with shared infant care responsibilities.
