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.

• White-faced sakis are active during the day, sleeping high (15 to 20 meters) in leafy trees to protect them from flying predators and weather.
• Typically, they have a lifespan of around 14 years in the wild and have lived up to 36 years in captivity.
• After the birth, the mother goes through breastfeeding-induced infertility, which lasts an average of 23 weeks.
• A pair often mates for life and is very devoted to each other. They strengthen their bond by grooming each other.
• White-faced sakis differ from other primates, including their close relative Chiropotes satanas. They are primarily leapers, which is how they travel about 70% of the time.
