Napo Saki Distribution

Napo Saki Characteristics

Napo Saki

The Napo saki[1] (Pithecia napensis), also called the Napo monk saki, is a species of saki monkey, a type of New World Monkey.

  • Its range includes parts of northern Peru and eastern Ecuador. Napo-Sakis show slight sexual dimorphism.
  • Male species have a black body, a dense coat of short white hairs on the crown, and a gray facial disc.
  • They also sport a reddish or orange ruff on their chest. Female species are gray overall, with no facial disc or crown coloration.
  • Their frill is brown and more subtle than that of the male species. Napo-sakis have particularly long hair around their faces and necks.
  • Their tails are also covered in long hair, giving them a very bushy appearance.

Napo Saki Facts

Pithecia Napensis

  • The species’ common name is derived from the Napo River in its locality.
  • Napo-Sakis have several physiological adaptations that help them survive high up in the rainforest.
  • They may exhibit piloerection to appear larger than they are, which can be helpful in territorial disputes or defense against predators.
  • Their forward-facing eyes allow them to see stereoscopically, a lifelong necessity in the trees.
  • A strictly arboreal species, Napo-saki sometimes descends to the lower levels of trees but rarely descends to the ground.
