Potamopyrgus is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the family Tateidae. [1]
Stimpson (1865) described the genus as follows: “Shell ovate-conic, imperforate; apex acute; whorls coronated with spines; outer whorl nearly two-thirds the length of the shell; aperture ovate, outer lip acute. Operculum corneous, subspiral. Foot rather short for the length of the shell, broadest in front and strongly auriculated. Tentacles very long, slender, and tapering. Eyes on very prominent tubercles. Rostrum of moderate size.”
This genus is endemic to New Zealand and south eastern Australia.
However, one species within this genus, P. antipodarum, has been accidentally introduced in many countries worldwide, especially in Europe and North America, and has become a problematic invasive species.
Species within the genus Potamopyrgus include:
The Buccinidae are a very large and diverse taxonomic family of large sea snails, often known as whelks or true whelks.
Gundlachia is a genus of minute freshwater snails or limpets, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails and their allies.
Tonna is a genus of large sea snails, marine gastropod molluscs in the family Tonnidae, the tun or cask shells.
Fluviopupa is a genus of very small freshwater snails that have an operculum, aquatic gastropod mollusks in the family Tateidae.
Rissoidae is a large family of very small and minute sea snails with an operculum, marine gastropod mollusks in the superfamily Rissooidea and the order Littorinimorpha.
Henry Suter was a Swiss-born New Zealand zoologist, naturalist, palaeontologist, and malacologist.
Liotella is a genus of minute sea snails or micromolluscs, marine gastropod molluscs in the family Skeneidae.
Philine is a genus of sea slugs or sea snails, marine gastropod molluscs in the family Philinidae, the headshield slugs or paper bubbles.
Bathytoma is a genus of deep-water sea snails, marine gastropod mollusks in the family Borsoniidae.
Daphnella is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae.
Onoba is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoidae.
Eulima is a genus of small, ectoparasitic sea snails, marine gastropod mollusks in the family Eulimidae.
Raphitomidae is a family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.
Stilifer is a genus of small ectoparasitic sea snails that used to belong in the family Stiliferidae. Most recent sources consider it part of the family Eulimidae, which also belongs to the superfamily Eulimoidea.
Scrinium is a genus of sea snails, marine gastropod mollusks in the family Mitromorphidae, in the superfamily Conoidea the cone snails and their allies.
Iravadia is a genus of very small, somewhat amphibious land snails that have a gill and an operculum, semi-terrestrial gastropod mollusks or micromollusk in the family Iravadiidae.
Rissoinidae is a large family of very small and minute sea snails with an operculum, marine gastropod mollusks, in the clade Littorinimorpha. Several genera that were previously part of Rissoinidae have been assigned to the Zebinidae family.
Tateidae is a family of very small and minute aquatic snails with an operculum, gastropod mollusks in the superfamily Truncatelloidea.
Opacuincola is a genus of New Zealand freshwater snails in the family Tateidae.
