Dang, was doing some reading on these and WOW! I had no idea they got this big.

Crocodile Monitor lizards have been documented to reach a length of 15 feet, with stories of 19 footers being told by tribesman deep in the heart of the Papua New Guinea jungles. These incredibly beautiful lizards are also known to have the longest tail, longest claws, and longest teeth of any living Monitor Lizard species. Maybe they should be classified as the “Longest Lizard”, while the Komodo Dragon classified as the “Heaviest Lizard”?
Another really interesting fact about a Crocodile Monitor’s teeth is with the exception of the Tyrannosaurus Rex, it is the only other reptile to have its top and bottom teeth scissor across each other.
