These small jungle animals sleep all day, hidden in hollow trees, and come out and roam, looking for food – typically insects and fruit – under cover of darkness. Night monkeys are actually the only nocturnal monkeys in the Amazon, with large brown eyes that enable them to see well at night. You can hear their grunts and screams and trills when you are out on the Aqua Expeditions skiffs after dark. The night monkeys live in family groups: mom, dad, and young ones.
