i was reading in a book that the "although it may be exceeded in length by the croc monitor, no other monitor equals the komodo dragon, in bulk (monitors,tegus,and other related lizard)
You already have your answer in your post. Croc monitors have proportionally longer tails and long slender bodies. Komodos are without a doubt the largest living lizard by weight.
Adult Komodos and crocs tend to be similar in length. Most of the reports of really long crocs are suspect. I imagine somewhere in the jungles there are probably crocs that are longer than the longest Komodo, but they would only weigh a fraction of the weight of an adult Komodo.
Crocs are secretive and not well known, while I would think that a record size Komodo wouldn't go unnoticed, what with all the locals, tourists, and science people in the area.
