Poisonous Rock Frog
   

Typical colour patterning.  Seen at  Panti Forest, Johor, Peninsular Malaysia.


Clinging to a moss-covered, stream-side boulder at Panti Forest, Johor, Peninsular Malaysia.


Specimen from Fraser's Hill, Peninsular Malaysia with less typical patterning comprising minor yellowish-green blotches on a brown background.

A large, distinctive frog to be found near fast-flowing streams, cascades and waterfalls up to 1500 metres altitude. The specimens shown here were found resting on fallen trees and moss-covered boulders next to a clear forest stream near Gunung Panti, Malaysia. All specimens were easily approachable.

The large size, typically Ranid body shape and the green and brown patterning serve to distinguish this species from the Common Greenback Hylarana erythraea

The species ranges from southern Thailand and West Malaysia (including Penang and Tioman islands), to Borneo, Sumatra and Java.
