Description

A small species of frog reaching up to nearly 2.5 cm in body length. It has a grey, light brown-yellow, brown, reddish-brown or olive-green back, with darker patches or longitudinal stripes. There is often a triangular patch between the eyes. The belly is cream-coloured or grey. The pupil is nearly round and the iris is gold. The legs have horizontal bars. Fingers and toes are unwebbed, both without discs.

Breeding Biology

Eggs are laid singly or in small clusters and attached to vegetation under the surface of the water in swamps, temporary pools, and lagoons. Tadpoles can reach a total length of up to 2.5 cm, and are red, brown, or gold in colour. They often remain on the bottom of water bodies, and take around one month to develop into frogs, although tadpoles in warmer areas may develop faster. Breeds during spring to summer in the wet season.

Similar Species

Looks similar to Crinia deserticola, Crinia fimbriata, and Crinia remota in its distribution, but has a different call, and lacks bright white spots on its back and limbs that are present in Crinia fimbriata.
