There are roughly 3,000 to 5,000 Komodo dragons left in the world, all of which live on the islands of Komodo, Gila Motang, Rinca and Flores in Indonesia, outside of the ones in captivity. This low population qualifies Komodo dragons as an endangered species.
Komodo dragons have lived in the Lesser Sunda Islands of Indonesia for millions of years, but humans have only known of their existence for roughly 100 years. Due to poaching, human encroachment and natural disasters, they have become endangered. Komodo dragons can reach up to 10 feet in length and weigh 300 pounds, making them the heaviest lizards on the planet.
