Night monkey - Photo by Posada Amazonas, Peru

This striking creature is a night monkey (also known as an owl monkey) who lives in the rainforest surrounding the Posada Amazonas ecolodge. Though this guy's picture was snapped during the daytime, night monkeys are the only species of monkeys that is nocturnal. Those huge eyes help it see at night while searching for fruits, leaves, and insects to eat. Night monkey sightings are quite rare – spotting one of them in the wild would be any ecotourist's dream!
