Key Identification Features
- Pseudophryne bibronii Günther, 1859 is a variable species that may actually represent more than one distinct species.
- These distinct traits make the quacking frog easily distinguishable from other species.
- Compared to other species in the same genus, Crinia georgiana is unique in having significantly larger testis mass, a feature linked to high levels of sperm competition in the species.
- Due to its unusual physical form, its distinctive features are thought to be inherited from early frog lineages that date back to the early Tertiary or late Mesozoic eras.
