The poison rock frog is a common inhabitant of lowland to upper-level rainforest along fast-flowing streams and rivers. This large frog is also a good climber though it usually sits on rocks and boulders along streams. The skin can secrete a potent toxin but the strength of it is not well-studied.


The entire dorsum and sides are a brilliant green, sometimes with dark patches while the eyes are large. The lips and ventrals are greyish white. The limbs are green with dark crossbars while the lips are white. In Southeast Asia, this frog occurs in Malaysia, Sumatra, Borneo and Java.
