A medium-sized monitor which can reach 1.5 metres, but specimens of this size are uncommon. Similar in appearance to the Malayan Water Monitor Varanus salvator, it is distinguished by the position of the nostrils which lie mid-way between the eye and snout.  

Its colouration comprises yellow spots on a brown-grey base. This mainly terrestrial species can be found in habitats as diverse as scrubland and rainforest, but is generally encountered as it digs amongst leaf litter searching for beetles and other insects. It may also be spotted clinging high up on tree trunks or exploring tree holes : its sharp claws make it an excellent climber.

The V. b. nebulosus sub-species ranges from Burma, Thailand and Indochina to West Malaysia, Singapore, Java and probably Sumatra.
