Description

A small species of frog reaching up to 2.5 cm in body length. It has a brown or light grey back, with longitudinal rows of black spots. The belly is bright orange-yellow. The under-surfaces of the arms and legs are pink-white, with brown specks. The pupil is horizontal, and the iris is dark brown. Fingers and toes are unwebbed, both without discs.

Breeding Biology

Eggs are laid as a small cluster on land in wet peat soil burrows hidden by vegetation near creeks. Tadpoles can reach a total length of up to nearly 2 cm and are brown in colour, with metallic bright blue specks. They never swim in water; instead they develop inside the broken egg jelly mass, feeding entirely on their own gut yolk reserves. They take at around three months to develop into frogs. Breeds during late winter to summer.

Similar Species

Looks similar to Crinia georgiana, Crinia glauerti, Crinia pseudinsignifera, Geocrinia alba, and Geocrinia leai in its distribution, but has a different belly colour to all of these species.
