Common Marmoset

Callithrix Jacchus

Common marmosets are New World monkeys, a term describing monkeys from South and Central America. They have white tufts of hair on the sides of their heads and on their forehead which identify them as common marmosets.

They live in polyandrous groups of 3-13, which means that a single female mates with multiple males who fluidly enter and leave the group. Typically, the core of the group will have one female, a male and their offspring. All members of the group assist with parental care. At birth the twin infants will be 40% of the mother’s weight.

Like all marmosets, common marmosets eat a diet high in tree sap and have specialised teeth to access this food type. Common marmosets will also eat a range of plants and animals including flowers, nectar, fruit, insects and spiders. They will also take small lizard’s, frog’s, and bird’s eggs.
