Cochliopidae is a family of small freshwater snails with gills and an operculum, aquatic gastropod mollusks.
Paludestrina d'Orbigny, 1840 is an archaic synonym, and has been placed on the Official Index of Rejected and Invalid Names by ICZN Opinion 2202.
This family is in the superfamily Truncatelloidea and in the order Littorinimorpha (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
Description
Cochliopidae snails are characterized by sharp, elongated spire-like structures, and can be found in rivers or brackish water.
