Komodo Dragons are lizards -  the largest living lizards on Earth and they can reach an impressive 3 m long.  The Komodo Dragon lives only on certain Indonesian islands. They are dominant predators and prey on large animals including buffalo, deer, pigs, and even other Komodo Dragons. Dragons ambush their prey and deliver sharp bite that includes toxic saliva. They are powerful swimmers, and young dragons live in trees to avoid being eaten by adults.  Fossils reveal that giant monitor lizards related to Komodo Dragons lived in mainland Australia until 30,000 years ago.
