1. Morgan Island, South Carolina, USA

When you see monkeys, you might think of some tropical island far away, but they are right here in America. About 4,000 rhesus monkeys live on Morgan Island, South Carolina, but they aren't native to those lands. So, how did they get there? These adorable faces were relocated from Puerto Rico after an outbreak of herpes virus B infection. 

Before the monkeys arrived, the island was uninhabited. It is illegal for people to visit the island for their own safety and the monkeys' safety. Although they look cute in pictures and movies, these monkeys are not the friendly kind. Only a handful of researchers are allowed to set foot on Morgan Island.
