Emilia’s Marmoset

Emilia's Marmoset

The Emilia’s Marmoset (Mico Emiliae), also known as Snethlage’s Marmoset, is a New World Monkey in the Callitrichidae family of monkeys, and is endemic to only certain states in Brazil. Emilia’s Marmosets live in extended family groups of between 4 and 15 individuals, and generally only one female per group breeds during a particular breeding season. The Emilia’s Marmoset defends their “home territory” in groups, ant the territory size is dependant on availability and distribution of foods and second-growth patches.


The Emilia’s Marmoset’s habitat is in the Amazonian lowland rainforest, as well as mixed open forest and forest patches of Brazil from south of the state of Pará and possibly entering contiguous parts of the state of Mato Grosso. They are usually content staying in the canopy of the forest where food is abundant, but can occasionally be found at ground level.


The diet of the Emilia’s Marmoset consists mainly of fruits, flowers, nectar, plant exudates (gums, saps, latex) and animal prey (including frogs, snails, lizards, spiders and insects). Emilia’s Marmosets have morphological and behavioral adaptations for gouging trees trunks, branches, and vines of certain tree species to stimulate the flow of gum, which makes up a considerable amount of their diet.
