The Tusked Frog (Adelotus brevis) gets its name from the greatly enlarged pair of teeth in its lower jaw.

Identification

A medium-sized species of frog reaching up to 5 cm in body length. It has a dark brown or dark grey back, with a butterfly-shaped marking between the eyes. The belly is marbled black and white. The pupil is horizontal and the iris is golden brown. The thighs and lower legs have bright red patches. Fingers are moderately webbed and toes are slightly webbed, both without discs. Males have two large protrusions resembling tusks on their lower jaw, and a very large head.

Habitat

The Tusked Frog is difficult to find as it hides among vegetation and logs besides puddles, streams and ditches.

Distribution

The Tusked Frog is found from the mid north coast of NSW to Eungella in mid north QLD along the coast, and extending inland to the ranges.



Communication

The Tusked Frog's call is a single 'tok' or 'cluck' repeated several times a minute.

Breeding behaviours

Eggs are laid as a foamy mass on the surface of permanent ponds, stream pools, water-filled crayfish holes, or cattle tracks. Tadpoles can reach a total length of 3.5 cm and are dark brown in colour, sometimes with a cream-coloured patch on the snout. They often remain at the bottom of water bodies and take around two months to develop into frogs. Breeds during spring and summer.
