Habitat and Ecology
It lives in the leaf-litter of the tropical rainforest. It uses the water inside the "ouriço" of Brazil nuts and small temporary pools for reproduction. Eggs are laid on the ground and the tadpoles are carried to pools to develop.
It is common where it is found.
Forest conversion, logging, fire and the international pet trade are threats to this species.
Conservation units are present within its range.
