Pygmy Marmoset

Meet the Smallest Monkey on Earth

Meet the Pygmy Marmoset

The pygmy marmoset is the smallest monkey in the world. It’s tiny, curious, and lives high in the forests of South America.

How Small Are They?

An adult weighs about as much as an apple. They’re often small enough to fit in your hand.

Where They Live

Pygmy marmosets live in the Amazon rainforest, especially in Peru, Brazil, Ecuador, and Colombia. They spend most of their time in the treetops.

What They Eat

Their favorite food is tree sap. They use their sharp teeth to make tiny holes in tree bark. They also eat insects and fruit.

Big Leapers

Even with their small size, they can leap far from branch to branch. Their long tail helps them balance.

Family Life

They live in small family groups. Most babies are born as twins. Both parents help take care of them.

How They Communicate

Pygmy marmosets use high-pitched calls that sound like whispers. These sounds travel through the forest and help the group stay connected.

Why They Matter

They play a role in rainforest ecosystems by spreading seeds and keeping insect populations balanced.

Threats They Face

Their biggest threats are habitat loss and illegal pet trade. Keeping them safe means protecting their forest homes.
