Found in lowland and subtropical rainforest in small fragments of Atlantic rainforest in Brazil.

Wild Diet

Insects (a particular favourite is army ants), sap, gum and fruit.


Geoffroy’s marmosets are sociable primates who live in groups of up to 10 individuals. The group will normally consist of a dominant female, her mate (who she will stay with for life) and their offspring.


The dominant female will normally give birth to twins, after a gestation period of 148 days. The father will carry the babies for the first two weeks of their life, during which they are completely dependant. After this they will be carried around by all members of the group who will take in turns to look after them. By 6 months the infants are weaned and independent, and they are capable of foraging for their own food.


Decline in numbers is due to habitat destruction, capture for the pet trade and for biomedical research. Geoffroy’s marmosets also suffer persecution in the wild due to a common fear that they are carriers of yellow fever and malaria.
