About Ranoidea cyclorhynchus (Boulenger, 1882)
This frog species is visually similar to its congener Ranoidea moorei. It has dark green or brownish patches with bronze or gold highlights on its back. This species can be distinguished from Ranoidea moorei by the numerous yellowish spots on the underside of its rear legs. Males can reach a maximum length of 65 mm, while females can reach 85 mm. The feet are unwebbed and have a prominent disc at each toe. The common name Copland's rock frog is sometimes mistakenly used for this species; the true Copland's rock frog is Litoria coplandi. This species is endemic to Southwest Australia, and is one of only four members of its diverse genus that occurs in the region. It is found in southern coastal areas, where it favors permanent water and granite outcrops. At its northernmost range extent, it can also be found in agricultural dams. Confirmed sightings have also been recorded at Middle Island in the Archipelago of the Recherche, and at Coragina Rock. Its natural habitats include rivers, swamps, freshwater lakes, and freshwater marshes. While habitat loss poses a threat to this species, it is currently classified as least concern for extinction. There are documented concerns that this species, the spotted-thighed tree frog, has recently become established on the Eyre Peninsula of South Australia. It may spread further east into the Murray-Darling Basin, where it could interbreed with or displace local threatened species.
