Silvery Marmoset

Silvery Marmoset

The Silvery Marmoset (Mico Argentatus) is a New World Monkey in the Callitrichidae family of monkeys, and lives in the eastern Amazon Rainforest in Brazil. The fur of the Silvery Marmoset is whitish silver-grey in color except for a dark tail. One of its more notable features is its naked, flesh-colored, ears which stand out from the rest of its skin. Fully grown adult Silvery Marmosets reach a size of 18 to 28 centimeters, and weigh between 300 grams to 400 grams.


Originally rain forest inhabitants, plantations have caused them to expand their range of habitat. Silvery Marmosets prefer to spend the night in tree hollows or in very close vegetation, and live together in small groups for safety. They prefer the food supply in the canopy of the forests, but can occasionally be spotted at ground level.


The diet of the Silvery Marmosets predominantly consists of tree sap and other plant exudates. To a lesser extent, they also eat bird eggs, fruit, insects, and small vertebrates if their preferred food source is in short supply.
