Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Ambatondradama, Ampoza, Antratrabe, Isalo, Kirindy, Morondava, Tsingy de Bemaraha.
It occurs from sea level to 900m asl in open areas, dry forest, savanna woodland, and degraded habitats (Nussbaum et al. 2008).
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).
Trends and Threats
It occurs in many protected areas (Nussbaum et al. 2008).
Possible reasons for amphibian decline
Intensified agriculture or grazing
Intentional mortality (over-harvesting, pet trade or collecting)
