Northern Pygmy Marmoset

Cebuella pygmaea

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

The pygmy marmoset is the smallest monkey in the world: an adult fits in the palm of a hand. It lives in the western Amazon, always close to watercourses, in family groups of between two and nine individuals. Its dietary speciality is gum: it opens holes in the bark of particular trees with adapted lower incisors and returns to them day after day to lick the oozing sap. It rounds out its diet with insects, nectar and small fruit.
