Cochliopidae is a family of small freshwater snails with gills and an operculum, aquatic gastropod mollusks.

Paludestrina d'Orbigny, 1840 is an archaic synonym,[1] and has been placed on the Official Index of Rejected and Invalid Names by ICZN Opinion 2202.[2]

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.[1]

2005 taxonomy
