This species is distributed in extreme southern Thailand (Satun), Peninsular Malaysia, Borneo (Brunei Darussalam, Malaysia and Indonesia) and Sumatra. It probably occurs more widely than current records suggest, especially in areas between known sites. It is a lowland species that is present at elevations up to 700 m asl.
Habitat and Ecology
It is an arboreal species found in forest and other dense vegetation along large lowland rivers. Breeding takes place in clear forest streams. Newly metamorphosed juveniles disperse through the surrounding forest and gradually become arboreal, moving up into the forest strata. It is unable to adapt to modified habitats.
It is common in Borneo and Sumatra, locally abundant in Peninsular Malaysia, and uncommon in Thailand (Dring, 1979).
The major threats to this species are riverine development, lowland forest clearance and the resulting sedimentation of streambeds.
It is present in a number of protected areas. Protection of areas of lowland riverine forest is the primary conservation measure required. It is protected by wildlife legislation in Thailand. It has been bred in captivity in Europe (Schmidt 1994).
