Growling grass frog native range. |
The growling grass frog (Litoria raniformis), also commonly known as the southern bell frog, warty swamp frog and erroneously as the green frog is a species of ground-dwelling tree frog native to southeastern Australia, ranging from southern South Australia along the Murray River though Victoria to New South Wales, with populations through Tasmania. This species' common names vary between states; the name southern bell frog applies to New South Wales, growling grass frog in Victoria and South Australia, and green and gold frog in Tasmania. This species has been introduced to New Zealand.
The growling grass frog is a very large, ground-dwelling tree frog up to 10 cm (almost 4 in) from snout to vent. It is a mottled bright green and bronze colour above, often with dark brown enameled bumps. It has a pale cream underside, with a faint cobbling pattern. A pale stripe runs from the side of the head down the flanks as a skin fold. The thighs are blue-green in colour.
There are a series of shallow bumps over its back. This frog closely resembles the green and golden bell frog (Litoria aurea), but is distinguished by the shallow bumps on its back, a shorter call, and a slightly different head and snout shape. The tympanum is visible in these frogs.
The tadpoles are also very large (up to 9.5 cm or 3.7 in). The tadpoles often have a coppery pigment along their sides and an iridescent green sheen along their backbones.
This species is associated with large swamps, permanent dam impoundments, ponds, and lakes (particularly ones with reeds) in woodland, shrubland, open and coastal areas.
