The white-faced saki[1] (Pithecia pithecia), also known as the golden-faced saki, Guianan saki, and Guyana saki, is a New World saki monkey species.
- White-faced saki displays sexual dichromatism and sexual dimorphism. Male species have black fur with white fur surrounding their face.
- Saki females have a shorter tan-gray coat with two vertical lines running from the eyes to the nose.
- Females can also have orange-brown fur that emerges around the chest and continues to the abdomen.
- At birth, adult males and females look very similar. A gradual color change occurs over a period of 3.5 to 4 years, during which time male saki becomes completely black with bright white faces.
- These saki monkeys have long, furry tails that act as a balance when leaping from one tree to another. Tails are not used to grab branches or objects.
