When I first saw this reptile, the giant monitor lizard at sungei buloh wetland, which was at least 200cm long, I was somewhat afraid as it was hissing and shooting its tongue like a snake. There were 4 of these around and they were lying in the shade, so I presume they just had their fill and having a siesta. It eats snakes, birds, and lizards.
A kind passer-by told me these were harmless.
