This Australian endemic is known from the northwestern Kimberley region of Western Australia, northern Northern Territory and into Cape York Peninsula of Queensland. It is also known from the Townsville region in Queensland. This region is very flat so the species is known only from low elevations. The extent of occurrence of the species is approximately 772,000km2.
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.
It is a common species.
There are no major threats to this species.
The range of the species overlaps several protected areas.
