There are lots of different species of primate living in the Manu Biosphere Reserve. But despite all belonging to the same order there is a lot of variation in these monkeys.
From the Large:
The Woolly monkey uses it’s prehensile tail to move through the trees easily despite it’s large size. The name comes from their soft curly hair which ranges from brown to black.
From a distance spider monkeys resemble giant versions of their namesakes moving through the trees. They can swing at very high speeds from tree to tree.
And Medium sized:
Capuchin monkeys are named after the order of friars with the same name. The friars wore brown robes with hoods that covered their heads and so explorers who first encountered these monkeys thought they resembled the friars.
All male squirrel monkeys are colour-blind, but only around a third of females are. This is because their genes for colour sensitivity are on the x chromosome, and so most females will end up with two different colour sensitivity genes but males will only get one.
To the Small:
Only one dominant female in a group of saddle back tamarins will breed, and she will almost always give birth to twins. After the birth the rest of the family group will look after the twins to share the burden.
The emperor tamarin is thought to be named after the German emperor Wilhelm II, since they both have rather impressive moustaches. Although the tamarin is much smaller than it’s namesake at around 25cm long (not including the tail).
