I adore this little Bolivian squirrel monkeys!!!!
They are one of the cleverest monkeys, they have very large brains compared to their body size.
Squirrel monkeys live in large groups called "troops". Troop may consist of up to 500 members, but it is usually smaller, composed of 40 to 50 members.
Communication inside the troop is accomplished via 25 to 30 different calls. Squirrel monkeys produced different sounds when they are searching for food, during the mating season and when they are threatened.
And last but not least a funny fact: squirrel monkeys spread urine on their hands and feet to mark their path when they are moving through the treetops. By following the scent, other members of the group can locate each other.
