Distribution
The Darling Escarpment from Bullsbrook south to Mt. Williams and east to Dryandra. Does not occur on the coastal plain.
Habitat
Occupies winter-flowing water courses, often on clay or granite.
Breeding
Males of this species excavate burrows in the banks of streams that become inundated after winter rains. Males call from within the burrow in autumn to attract females. If a female enters the burrow, the male will embrace her (amplexus) and she will deposit the eggs at the bottom of the burrow in damp soil. Rising water caused by winter rain eventually floods the burrows, allowing the newly developed tadpoles to wriggle free of the egg mass and swim in to the water body.
Call
A low pitched owl-like "hoot" repeated frequently.
Eggs
The egg masses of this species are white and foamy. As many as 500 eggs may be laid in each mass.
Tadpoles
The body is dark brown to pale grey with a series of thin, light coloured lines on either side. They grow to 6 cm, with the tail twice as long as the body with low fins and a rounded tip. Development time is from eight to twelve weeks.
