Squirrel monkeys are one of the cleverest monkeys, which means they need a lot of intellectual stimulation to prevent distress caused by boredom. In the wild they live in ‘troops’ of up to 500, but usually more like 50. They scent mark their territory by spreading urine on their hands and feet which marks the path where they walk. They live for up to 20 years.
Squirrel monkeys are one of the smaller species of primates. They are fairly common in the pet trade.
