The build is robust and the limbs are relatively short. Maximum length is around 6 cm. The back is brown to dark grey with a mottling of white or grey (no yellow as in moaning frogs). Pale coloured tubercles (bumps) are usually present on the lower flanks. Males possess the nuptial spines that the similar-looking moaning frog males lack.

Distribution
Found from Geraldton south to Walpole and east to Albany. Not found on the coastal plain apart from a few locations at the base of the Darling Range.
Habitat
This species occurs on white sands (where the scientific name comes from) or clays mainly in Jarrah forest.
Breeding
The males, like all members of the genus Heleioporus, burrow in low lying areas which become inundated after autumn and winter rains. Males call from within the burrow to attract females after which eggs are deposited at the bottom of the burrows in damp soil. Rising water levels of swamps and creeks caused by rain eventually flood the burrows allowing the newly developed tadpoles wriggle free of the egg mass and swim out of the burrow. Males only call for a month or so after the first rains in autumn.
Call
A short high-pitched "put put put put." repeated frequently. Sounds like a speeded-up whooping frog call and has been likened to an outboard motor.
Eggs
The eggs masses of this species are white and foamy. As many as 200 eggs may be laid in a burrow.
Tadpoles
Sand frog tadpoles grow to 5 cm with the tail only one and a half times body length. The body is dark brown to pale grey with a series of thin, light coloured lines on either side. Froglets metamorphose in September and October.
