Glyptophysa georgiana

The sinistral (left-coiling), oblong, oval-shaped shell of Glyptophysa georgiana is yellow-brown in color, and about twice as long as it is wide. It has a very short spire, a structure formed from stacks of whorls. This species has a relatively smooth shell among the genus Glyptophysa, though not as smooth as the similar Physella acuta. The periostracum (outer layer of the shell) may be decorated with hairs or fine spiralling lines, though these characteristics are variable within populations. This species may not be distinguishable from others in the genus based on shell characteristics alone, and must be accompanied by the location the specimen is found.

Species of Australian Glyptophysa may not be distinguishable by shell characteristics alone, with state borders proving useful for identification. Glyptophysa georgiana has been recorded from fresh water in coastal areas of southwestern Western Australia. Other sources include Tasmania as a valid location. The species is likely to make use of any body of fresh water as habitat, and is found in both fast (lotic) and slow-flowing (lentic) waters. It does not inhabit brackish or salt water. As of 2026, the IUCN lists this species as data deficient due to taxonomic confusion surrounding the genus. However, they comment that the species is likely relatively common, and may be considered least concern once the taxonomy is validated. Its habitat faces threats of degradation by agriculture, logging, and development, though no conservation actions are in place for this species. This species has been recorded in the stomach contents of several fish species, including the minnows Galaxias occidentalis and Gambusia holbrooki, the perch Edelia vittata, and the nightfish (Bostockia porosa).
