I saw three or four monitor lizards in Borneo. One was in a tree, and it came down and wandered across in front of me while I was alone in a wildlife preserve. The others we saw along the banks of the Kinabatangan river. These look exactly like Komodo dragons, only smaller. They clean up anything dead in the rainforest quite quickly as they are effective scavengers. It is interesting to see their forked tongues and tough, scaly skin.
