The tusks of the tusked Frog are modified teeth, found in the mouth, on the lower jaw.

The tusked frog is a unique frog within Australia, as it is the only species where the female is smaller than male.

Male tusked frogs have a disproportionally large-sized head, compared to the body, and females have a smaller proportioned sized head than males.

Twenty-two species of amphibians have been found in the park, including isolated populations of Litoria fallax (eastern Sedgefrog) and Adelotus brevis (Tusked Frog).

Males in species such as the tusked frog (Adelotus brevis) and the fanged frog (Limnonectes kuhlii) use fangs and tusks as weapons to defend their calling sites.

The tusked frog (Adelotus brevis) is a species of ground-dwelling frog native to eastern Australia from Eungella National Park, Queensland south to Ourimbah, New South Wales.
