Goeldi’s monkey

Goeldi's monkey, also known as Goeldi's marmoset (Callimico goeldi), is a species of primate found in the western Amazon River basin. It is part of the marmoset family (Callitrichidae) and is distinguished by its black, maned appearance. Unlike other marmosets, Goeldi's monkey does not typically bear twins, and it possesses a third set of molars. These monkeys are active during the day and primarily eat insects, fruit, tree sap, and other small animals. They move quickly and use claws on their digits to scamper along branches. Goeldi's monkey is considered a member of the marmoset family, despite some unique characteristics.1
