Thats a nice close up of the lizard, Sabyasachi. The pupils look dilated and the scales are worn and shiny, looks to be an aged adult. I have also noticed with monitors that they can let you come fairly close, in one of my trips to the Bornean rainforest last year I saw a fighting pair of monitor lizards and asked my boatman to go as close as possible without disturbing them. We could go as close as 2 feet from the bank and the lizards didn't get intimidated by my presence and were busy with themselves. Thanks for sharing.
