Get to Know Me

Common marmosets are small monkeys with long tails that call the treetops of North-east Brazil home. Their fur is a mix of brown and white, making it look soft and silky. The special name scientists use for them, Callithrix, comes from Ancient Greek and means ‘beautiful fur.’ These monkeys have claws, not regular nails, which help them quickly climb up trees. Their ability to scamper up tree trunks and branches is impressive, thanks to these handy claws.

They use a variety of vocalizations, including trills, chirps, and whistles, to convey messages within their group. Despite their small size, common marmosets are highly adaptable and display quick learning abilities.


Common Marmoset typically live for about 8 to 15 years in their natural habitat. Their longevity is influenced by factors such as the conditions of their habitat and the risks of predation. Interestingly, when provided with proper care and nutrition in captivity, these little adventures can surpass their wild counterparts, extending their lifespan to reach up to 20 years or more.

Weight & Diet

Weighing in at just 300 to 500 grams, they are about as light as a bag of chips. Common marmosets are also like little chefs in the rainforest. They munch on the usual stuff like fruits and bugs, but here's the fun part, they're also experts at eating tree sap and gum! With special teeth, they nibble on tree bark to get these gooey treats. It's like having a sweet snack while swinging in the trees.
