Geoffroy’s monk saki^[1], also called monk saki, is a species of saki monkey, a New-World primate native to South America.

• Always desperate for a haircut, Geoffroy’s monk saki is a smaller primate with dark, shaggy fur.
• Their partially bare face is surrounded by a densely fringed hairstyle reminiscent of his namesake, a monk.
• Their bodies are typically black with light gray feet and hands, giving them an aged appearance. However, they can grasp branches with long, dexterous fingers.
• Their short hind limbs are designed to leap great distances quickly, perfect for living high in the trees.
• A Geoffroy’s monk saki tail is as thick and hairy as the rest of the body. However, it isn’t prehensile and sometimes hangs over branch edges like a particularly dirty feather duster.

• Geoffroy’s monk saki weighs as much as a giant rabbit.
• A monk saki is one of seven species of New-World arboreal monkeys with a bushy, feathery tail.
• This tiny primate is very nervous around humans and has abnormal disturbances; therefore, there is very little data on the daily life of Geoffroy’s monk saki.
• They are diurnal and four-legged leapers; they usually move on all fours but can be seen swinging bipedally on large branches before jumping to another tree.
• Adults can identify their mate by a specific vocalization. Still, many of Geoffroy’s monk saki’s modes of communication seem designed to express aggression.
