Common marmosets live together in family groups of four to 15 animals.
The groups have a strict ranking, ordered by the dominance and aggressive behaviour of the group leader. These monkeys use their specialised claws to establish a firm grip on tree trunks and gnaw little holes in the bark with their lower incisors and canines. This causes the tree to produce more sap, which is used to seal injuries to the bark. This tree sap is a valuable source of carbohydrates and minerals.
