Goeldi’s monkeys are most frequently found travelling and foraging on the ground or among the lower branches of the forest. Their sharp curved claws help them to grip the branches. They move rapidly through the trees – often progressing by vertical clinging and leaping at about 2 metres from the ground. They eat fruit, insects, spiders, lizards, frogs and snakes. The Goeldi’s call is very high pitched and squeaky.
