Habitat
The Santarem marmoset inhabits the tropical rainforests of the Amazon basin, particularly in northern Brazil near the Tapajós River. They prefer dense, secondary forests with plenty of trees for climbing and foraging, often staying close to river edges or flooded areas. This species avoids open areas and thrives in humid, lowland environments.
Diet
Santarem marmosets primarily eat fruits, insects, and tree sap, with occasional small vertebrates like lizards or frogs. They forage in small groups during the day, using their sharp teeth to gnaw on bark for gum and sap. Feeding peaks in the early morning and late afternoon when food sources are most abundant.
Behavior
Santarem marmosets live in small family groups of 4-15 individuals, typically led by a dominant breeding pair, and exhibit strong social bonds through grooming and vocalizations. They are diurnal and highly arboreal, spending most of their time in trees and marking territories with scent glands. These monkeys are agile and territorial, defending their areas with alarm calls and chases.
Conservation Status
The IUCN lists the Santarem marmoset as Vulnerable due to ongoing habitat loss from deforestation and agriculture. Population trends are declining, with major threats including fragmentation of rainforest habitats and potential capture for the pet trade.
