Life History, Abundance, Activity, and Special Behaviors

Habits: Calling and foraging both during day and night. In Kirindy, highest levels of calling activity were recorded at night near pools. One clutch, containing 35 yellowish eggs was found under a fallen log close to a forest pond.

Calls: Series of short double-click notes.

Breeding occurs in permanent and temporary still waters. The eggs are laid on land near water, and the larvae develop in temporary and permanent pools, and sometimes in brooks (Nussbaum et al. 2008).

Threats

Major Threats
It is an adaptable species, and there are few, if any, habitat-related threats, though it might be impacted by fires and by overgrazing by livestock. It is has been suggested that over collecting for commercial and private purposes is a threat, but it is only traded in low numbers.
