Callithrix jacchusLC— Least Concern
The common marmoset is a small New World monkey native to the forests of northeastern Brazil, easily recognized by its white ear tufts and banded tail. It specializes in feeding on tree gum and sap, supplemented with insects and fruit, and typically gives birth to twins twice a year, relying on cooperative care from the whole group. Widespread and adaptable, it is classified as Least Concern by the IUCN.

- The common marmoset is native to northeastern Brazil, and has spread into southeastern Brazil since the 1920s through releases of captive animals. Source
Did You Know?
- In 2014, a female common marmoset became the first New World monkey to have its genome fully sequenced, revealing 21,168 genes. Source
- Common marmosets typically give birth to fraternal twins twice a year, a reproductive burden that has driven the evolution of cooperative infant care within the group. Source
- Most of their fingers bear claw-like nails called tegulae, an adaptation that helps them cling to vertical tree trunks. Source

FAQ
- What do common marmosets eat?
- They specialize in gouging tree bark to feed on the exuding gum and sap, which can make up 20 to 70% of their feeding time, supplemented by insects (24 to 30%) and fruit, flowers, and small prey. Source
- How many babies do common marmosets have?
- They typically give birth to fraternal twins twice a year, and because this is demanding for the mother, other group members help carry and care for the infants. Source
- Why was the common marmoset genome significant?
- In 2014, it became the first New World monkey species to have its genome fully sequenced, an important reference for biomedical research. Source
