Tassel-eared marmosets have large silvery ear tufts in a fan shape. Their general body colour is brown, and they have a banded tail.
They inhabit Central Brazil, south of the Amazon.
They prefer secondary forests, often with dense vines.
The majority of the tassel-eared marmoset's diet is made up of fruit, but they also feed on small animals and insects.
Tassel-eared marmosets live in groups of 8-15, typically multi-male and multi-female. They have a home range of 13-28.5ha and they are thought to scent-mark their territories with scent from the inside of their arms. They are diurnal and arboreal, sleeping at night in vine-covered trees. They move quadrupedally along the forest floor and make short leaps through the forest canopy.
They have a gestation period of around 140-145 days, giving birth to 1-2 young.
This species is not on the 2000 IUCN Red List of threatened species.
