Description

Tusked frogs are small, flattened frogs up to 50mm long, olive green to almost black above and black and white below, with orange-red patches in the groin and on the hind legs. Males have a large wide head, and the species is unusual amongst frogs in that males are normally larger than females. The call is a single “cluck” repeated slowly. Both sexes bear sharp tooth-like tusks in the lower jaw that fit into depressions within the upper jaw; these tusks are larger in males and may be used agonistically.

Distribution

Coast and adjacent ranges from central Queensland to southern NSW. Tusked Frogs were once found west to the New England Tableland and North West Slopes (Nandewar bioregion) but are now very rare there, and the population in these regions has been listed as an Endangered Population under the Threatened Species Conservation Act. They remain more common in lower elevation coastal areas.

Habitat and ecology

  • Rainforests, wet forests and flooded grassland and pasture. They are usually found near creeks, ditches and ponds, and call while hidden amongst vegetation or debris.
  • The species breeds from Spring through to Summer, with a peak during late Spring.
  • Eggs are deposited in nests under leaf litter or other cryptic sites such as old yabbie burrows near or in water.
