Description

A medium-sized species of frog reaching up to 5 cm in body length. It has a brown or green back, with or without brown or olive-green mottling. There is a gold or brown stripe from the tip of the snout to past the arm, becoming spots on the side. There is often a green stripe along the upper lip if the back is brown. The belly is white or yellow. The pupil is horizontal and the iris is gold. The backs of the thighs and the groin are yellow or orange. Fingers are slightly webbed and toes are fully webbed, both with large discs.

Breeding Biology

Eggs are laid as a single cluster that is attached to rock crevices under the surface of the water in streams. Tadpoles can reach a total length of up to 4 cm and are dark brown in colour, with many small gold spots. They often remain at the bottom of water bodies, and take around three months to develop into frogs. Breeds during spring and summer.

Distribution

Formerly found in a wider area of the Snowy Mountains in NSW and VIC, but has declined severely due to the amphibian chytrid fungus, and is now known only from several small populations in VIC and one in NSW. There is a captive breeding program currently in place to help prevent their extinction.
