Description

The beautifully patterned Green and Gold Frog has a green to golden brown upper surface with scattered warts and gold or brown blotches. The undersurface is white and granular.

Also known as the Growling Grass Frog (in Victoria), Southern Bell Frog or Warty Bell Frog, it is Tasmania's largest species, with females growing to 90 mm. Males reach 65 mm.

Breeding

The Green and Gold Frog breeds in spring and early summer. Several thousand eggs are laid. Larval development lasts 12 - 15 months. The tadpoles - also the largest of any Tasmanian species - can reach 100 mm in length. Metamorphosis occurs in summer and autumn, with the young frogs (metamorphs) having a similar bright green colour to the adults.  Sexual maturity is reached after 2 years. They can live for over 20 years.

Distribution and Habitat

It lives in weedy ponds, dams and streams and is most common in northern Tasmania, with some occurrences in the east and south of the State, although numbers are decreasing in the south. It is one of only two species of Tasmanian frog that bask (the other being the Tasmanian Tree Frog).

The Green and Gold Frog is listed as vulnerable, as population levels have declined markedly due to habitat loss, range contraction and possibly chytrid infection, particularly in the south of the State and the Hobart region.
