River Toad
   

Large specimen seen at Langkawi,  Peninsular Malaysia.


Another large specimen showing pink and blue mottling on the belly : Fraser's Hill, Peninsular Malaysia.
 

River Toads can often been found a long distance from any water course, such as this pinkish specimen on a roadside bank in Fraser's Hill, Peninsular Malaysia.

This is the second largest of the Bufo genus in the region, after the Giant River Toad Bufo juxtasper. Females can reach a maximum size of 12 cm (snout-to-vent); with the addition of powerful back legs this toad can appear very large indeed. 

The species inhabits lowland primary and secondary forests, and at night it may be found amongst rocks and sandbanks by streams and rivers. It is identified by its large size and broad head.  

It ranges from Burma through Thailand and West Malaysia to Sumatra, Java and Borneo. The absence of fast-flowing rivers means it is absent from Singapore.
