Black ear tufts, white forehead with light facial hair. The back and tail are banded.

FACTS:

  • Diurnal and arboreal; sleeping at night in tree holes or other shelter.

  • When threatening a human, these marmosets put their ear tufts forward and fluff up their fur to make themselves look larger. They also make a rapid and continuous vocalization. High-pitched whistle is a warning signal.

  • Live in groups of 4 - 15 individuals that have overlapping home ranges. Sleep huddled together in the wild. Dominance is maintained through aggressive interaction.

  • Quadrupedal; they run and hop in trees and bushes and are capable of leaping. Movements are quick and jerky.

  • In captivity, these marmosets may catch and eat sparrows that fly into their cage.

  • Specialized short lower canines are used to perforate tree bark, inducing the flow of gums and sap.

  • Forelimbs are shorter than hind limbs

  • Thumb is not opposable
