Both fore and hind limbs are robust and powerful, and the digits of the hands are webbed as well as those of the feet.

This frog is a dark greenish-black in colour with some faint pale green hatching and spotting on the hind limbs.

[3] This frog is endemic to the western Philippines where it is present on Busuanga, Culion, Balabac, and Palawan.

Its typical habitat is fast-flowing, unpolluted streams in lowland tropical forests at elevations below 800 m (2,600 ft) asl.

This led researchers to hypothesize that development may be direct without an intervening tadpole stage.
