Our Common Marmoset, found at Southwick's Zoo in Mendon MAFacts

  • Marmosets are very small monkeys found in northern Brazil. Their name comes from the French word “marmouset” which translates to “dwarf”.
  • They are arboreal and spend their time in the trees. Marmosets have claw like nails that allow them to cling to trees and climb like squirrels. They can climb vertically as well as run and leap across branches.
  • Marmosets are vulnerable to a number of predators due to their diminutive size. They have an alarm call to alert the rest of the troop when potential danger is nearby.
  • Females often give birth to twins. Infants cling to their mother’s back for their first two weeks. The father helps care for their young as well.
  • Marmosets communicate vocally and visually through facial expressions. Scent also plays an important role in how they communicate with one each other.

Did You Know?

Marmosets are omnivores and feed on insects, fruit, flowers, and sap. They have chisel-shaped incisors to gnaw holes in the bark of trees to get lick and scoop out the sap. Saps and gums make up much of their diet when fruit is scarce.
