Description

A large species of frog reaching up to 10.5 cm in body length. It has a brown or bright green back, with or without dark brown patches. There is a dark brown stripe from the tip of the snout to the side, and sometimes a pale, thin longitudinal stripe along the middle of the back. The belly is white, and the male has darker mottling on the throat. The pupil is horizontal and the iris is gold. The backs of the thighs have brown patterns. Fingers are unwebbed and toes are one-third webbed, both without discs.

Breeding Biology

Eggs are laid as clusters that sink under the water and scatter in ponds. swamps, flooded grassland, and creek pools. Tadpoles can reach a total length of up to 8 cm, and are pale gold, pale silver, brown, or olive-grey in colour. They often swim at all depths of water bodies, and may take less than one month to develop into frogs. Breeds during spring to summer in the wet season.

Similar Species

Looks similar to the many Cyclorana species in its distribution, but is generally larger than most, except for Cyclorana novaehollandiae and Cyclorana platycephala. Cyclorana novaehollandiae lacks brown patterns on the backs of the thighs, and Cyclorana platycephala has more toe webbing.
