Potamopyrgus is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the family Tateidae.[1]


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.
