Habitat
This species primarily inhabits the tropical rainforests of the western Amazon in Brazil, especially around the Rio Acari and nearby riverine areas. They prefer dense, humid forests with tall trees for canopy movement and access to water sources. These marmosets are adaptable to both primary forests and secondary growth, though they avoid open or heavily disturbed areas.
Diet
Rio Acari marmosets mainly eat fruits, insects, and tree sap, which they extract using their specialized teeth. They forage in small groups during the day, often in the upper canopy, and supplement their diet with flowers, nectar, and occasionally small vertebrates like lizards. Feeding activity peaks in the early morning and late afternoon when resources are abundant.
Behavior
Rio Acari marmosets live in small family groups of 4-15 individuals, exhibiting cooperative breeding where multiple members help care for the young. They are diurnal and highly agile, spending most of their time in trees with quick, acrobatic movements to evade threats. These marmosets are territorial, using vocalizations and scent marking to defend their home ranges and communicate within the group.
Conservation Status
The IUCN classifies the Rio Acari marmoset as Vulnerable due to ongoing habitat loss from deforestation and agriculture. Population trends are decreasing, with major threats including fragmentation of their rainforest habitat and potential hunting pressure.
