Habitat and Ecology: The species is found in sparsely timbered savannah, sclerophyll woodland and grassland on clay soils. It spends most of its life buried underground and emerges only after heavy rain when it can be found on low-lying swampy ground, which remains saturated after rain. It breeds after heavy rains in shallow flooded areas. Males call whilst floating in water and their bodies are inflated with air from their distended lungs. About 500-1400 eggs are laid in long chains tangled in submerged vegetation. Tadpoles hatch and complete development in 8 weeks.
