Bare-eared Squirrel Monkey Characteristics

Bare Eared Squirrel Monkey

The bare-eared squirrel monkey[1] also called the golden-backed squirrel monkey, are a subspecies of the Saimiri sciureus group native to the tropical forests and jungles of South and Central America.

  • Bare-eared squirrel monkeys have masks of white fur around their eyes and black or dark brown around their mouths and chins.
  • Species in the Saimiri sciureus group have a “gothic” arch. The white fur rises dramatically, and the darker fur on the head forms a deep “V” between the eyes.
  • The bare-eared squirrel monkey differs from other species because it does not have ear tufts.
  • Also, it is yellowish or orange on its forearms, feet, and hands with a brownish-gray head.

Bare-eared Squirrel Monkey Facts

Saimiri Ustus

  • Their small size makes squirrel monkeys vulnerable to a wide range of predators throughout their range, including birds of prey, felids, and snakes.
  • Bare-eared squirrel monkeys can only sweat through the palms of their feet and hands. This makes their feet and hands feel damp when touched.
  • Their females have a pseudo-penis which they use to show dominance over smaller monkeys just like their male counterparts show dominance.
  • Unlike other New World monkeys, the tail of bare-eared squirrel monkeys is not used for climbing but as a kind of “balance pole” and a tool.
  • The genus name is of Tupi origin (sai-mirim meaning sai “monkey” and mirim “little“) and was used as an English name by early researchers too.
