Clouded Monitor (Varanus nebulosus)
Island Club Road, 14th March 2017

This very young Clouded Monitor was seen near the entrance of Island Club Road. It had most likely been run over by a passing vehicle.

Whether the Clouded Monitor is a subspecies of the Bengal Monitor (Varanus bengalensis) or a distinct species is still a matter of some debate; some sources still lump the two of them together.

Clouded Monitor (Varanus nebulosus)
Bukit Drive, 15th June 2015

This Clouded Monitor was seen on a road at the edge of Hindhede Nature Park. It had most likely been run over by a passing vehicle.

Two eggs were also found on the road close to the carcass. If they did come from the Clouded Monitor’s body, it suggests that this individual was a gravid female. It’s possible that the eggs were forced out of the body from the impact of a vehicle, maybe even the same vehicle that had killed the lizard itself.

Whether the Clouded Monitor is a subspecies of the Bengal Monitor (Varanus bengalensis) or a distinct species is still a matter of some debate; some sources still lump the two of them together.
