Range & Habitat
Upper Amazon in Brazil, North Bolivia, Peru, Columbia and Ecuador. Their habitat is dense undergrowth of non-riverine forests and bamboo forests.
Reproduction & Growth
Goeldis live in extended family groups. There may be only two breeding females in a group. These females have a single young twice a year. Their gestation period is 150-160 days. The male helps carry the young 7-10 days after birth. The young become independent in 2 1/2 months. The whole group takes part in carrying the young and surrendering food morsels to them, the breeding females and infant carriers.
In the Wild: Fruits, insects, spiders, lizards, frogs and snakes. In the Zoo: Marmoset diet, bananas, apples, oranges, eggs, kale, cooked carrot or yams, monkey biscuits, grapes, raisins, cantaloupe and mealworms. In the Zoo: Fruits, vegetables, monkey biscuits, meal worms and marmoset diet.
Some scientists believe that the Goeldis is a more developed primate, and is sometimes classified as its own species because it shares traits with both the tamarins and the capuchin-type monkeys. They have long limbs and tail for climbing and hanging from trees. The Goeldis vocalize in a very high pitched squeaky call as well as chirps and clicks.
They are rare throughout their range. Slash and burn agriculture has destroyed much of the tropical rainforest they live in. Because they are rare and internationally protected, poachers can sell them for a large profit on the black market.
