Habitat and Ecology
It lives on the forest floor in leaf-litter in both relatively pristine and disturbed rainforest. It lays its eggs on land and guards them until they hatch. The tadpoles then wriggle onto their parent's back (although it is not clear whether or not it is the male or the female that carries the larvae).

Life History, Abundance, Activity, and Special Behaviors

Learn more about this article

During amplexus, the female deposits the eggs in a terrestrial nest site, where it is thought that they are then guarded by the male. When they hatch, the tadpoles climb onto the male's back until they undergo metamorphisis.

Major Threats
The main threat is habitat degradation, mainly due to fire and invasive species, but it is not thought to be seriously threatened since it is somewhat adaptable to secondary habitats. It might be inherently at risk because of its small range.
