Number three is the only island on earth shared by three countries: Brunei, Indonesia, and Malaysia. Borneo is home to one of the world's oldest rainforests, which is located on the opposite side of the earth as the Amazon in Brazil. The 130 million-year-old jungle is teeming with exotic and rare wildlife, including clouded leopards, saltwater crocodiles, Dayak fruit bats, Irrawaddy dolphins, and Bornean orangutans. Indonesians call the island “Kalimantan,” which comes from a Sanskrit word meaning “burning weather island” because of its hot and humid climate.
