A large species of frog reaching up to 7 cm in body length. It has a bright green, olive-green or brown-green back, with dark green or gold patches and often a green longitudinal stripe down the middle. The belly is white. The pupil is horizontal and the iris is gold. Fingers are unwebbed and the toes are fully webbed, both without discs. It is now the only Australian species known to be almost entirely aquatic.
Eggs have not been described, but are laid under the surface of the water in permanent swamps, ponds, lagoons, and dams. Tadpoles can reach a total length of up to 8 cm, and are grey-brown or black in colour. They often remain at the bottom of water bodies, and swim in ball-shaped schools. It is unknown how long they take to develop into frogs. Breeds during summer in the wet season.
Does not look similar to any other species in its distribution.
