The most common monitor lizard among the three found in Singapore is the Malayan water monitor (Varanus salvator) that can grow up to 3m long. The other two species, the clouded monitor lizard (Varanus nebulous), and the rarest Dumeril’s monitor (Varanus dumerilii) can grow to a length of 1 to 1.5m. Monitor lizards are mostly carnivorous; some also scavenge on carrion. It can be found in forests, mangrove swamps, and even man-made canals.

The monitor’s saliva contains over 50 bacteria that infect and kill their prey slowly. Is this true?
The carrion meat that get stuck in the monitor’s teeth are teeming with bacteria that can cause infections in the bite wound. However, the main cause of death of preys is the venom secreted by the monitor.

They are naturally shy and would rather stay away from humans. Like most wild animals, they do not attack unless provoked. As long as you keep your distance and leave them alone, you will be fine.
