Ever held a finger monkey before? What’s a finger monkey, you ask. Well, believe it or not, it’s a monkey the size of a human finger. They got their name because of their size and the fact that they cling to your fingers when you try to hold them. The planet’s smallest living primate, finger monkeys are also known as pocket monkeys or tiny lions.
Indigenous to the rain forests of Brazil, Peru, Ecuador, and Columbia (where they possibly export drugs to other finger monkeys), the common finger monkey can grow up to 14 inches. Don’t let a finger monkey’s looks fool you. Its claws are extremely sharp, and when a provoked, these pygmy marmosets can wreak havoc like you’ve never seen.
