Malayan Water Monitor Lizard

Juvenile Varanus salvator.

This 'biawak air' entered my backyard yesterday evening while my sons were playing with their new hamsters.
They thought that the monitor lizard going to catch their pets, and chased that lizard away.
It ran away and entered the rain gutter via a downspout.
It was still up there on the roof by 7.30pm .



Brightly yellow markings on the body and bands of yellow-grey/bluish on the tail. The compressed tail can be twice as long as its body.
