Valvata piscinalis
Taxonomic Group: Mollusks-Gastropods


Valvata piscinalis is a small freshwater snail commonly known as the European Valve Snail and the European Stream Valvata. It is native to lakes, rivers, and slow-running streams in Europe, western Siberia, and the Caucasus. It was first reported in North America in 1897 and is currently found throughout the Great Lakes/St. Lawrence area. It was not noted in an estuarine environment until it was found in the tidal Hudson River in 1985. It cannot withstand large variations in salinity and has a low tolerance of 2 – 3 PSU. It is generally found on silty vegetated substrates and in highly disturbed habitats, such as canals. No impacts have been reported for this species in North America.
