Justification:
Listed as Least Concern in view of its relatively wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Habitat and Ecology
[top]
| Habitat and Ecology: |
It lives in the vicinity of streams in forest, and only survives in secondary habitats at higher elevations. They lay eggs on leaves close to water, but not above water. The tadpole falls to the ground and develops on land (it never enters water). The tadpole does not have a fully developed alimentary canal, and so it does not eat, but instead is dependent on its yolk. The alimentary canal is only developed and functional at the time that the tadpole develops into a frog. This process is referred to as semi-direct development.

| Systems: |
Terrestrial; Freshwater |
| Major Threat(s): |
It is presumably threatened by the loss of forest habitat for agriculture, logging and human settlements.
