- Group
- Land mammals
- Class
- Mammalia
- Order

- Callithrix
It is a monkey originally from northeastern Brazil that lives in places such as scrubby woods and wetlands.
It has white tufts on its ears and white hair on its forehead, and its tail is striped black and silvery gray.
With specially shaped lower front teeth it makes holes in tree trunks to feed on sap, and it eats more sap than other marmosets.
How the Common marmoset lives
They are active during the day and live around forest edges rather than deep within the forest. They eat insects, spiders, fruit, flowers and nectar. Groups may include adult marmosets and their offspring.
