Thickshell pondsnail
species of gastropod
Ladislavella utahensis, common name the thickshell pondsnail, is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusc in the family Lymnaeidae, the pond snails. This species is endemic to Utah Lake in the United States. The last living snails were found in the early 1930s.
Shell description
The shell is globose, somewhat umbilicated and irregularly costate. The color of the shell is light horn and nearly pellucid. The spire is rather small and conical. The shell has from 4 to 4 and half convex whorls, that are somewhat flattened above, giving rather a shouldered appearance to the whorls. Whorls are rapidly increasing in size. The last whorl is inflated, with numerous rather marked transverse costae and minutely wrinkled. The suture is somewhat deep, regularly impressed.
Begin with the source’s own compact description: “Thickshell pondsnail” is species of gastropod. The dossier treats that line as a proposition to test through Thickshell, pondsnail and species, not as a finished interpretation.
Why this record matters
The phrase “species of gastropod” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Oct 5, 2025. The linked authority identifier is Q123194083. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
