Cochliopidae is a family of small freshwater snails with gills and an operculum, aquatic gastropod mollusks. Paludestrina d'Orbigny, 1840 is an archaic synonym,[2] and has been placed on the Official Index of Rejected and Invalid Names by ICZN Opinion 2202.[3]

This family is in the superfamily Truncatelloidea and in the clade Littorinimorpha (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).


Cochliopidae snails are characterized by sharp, elongated spire-like structures, and can be found in rivers or brackish water.[2]

2005 taxonomy[edit]

The family Cochliopidae consists of 3 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):[4]


Liu et al. (2001)[5] have recognized 34 genera with more than 260 species within the subfamily Cochliopinae.[5]

Strong et al. (2008)[1] have recognized 246 freshwater species within Cochliopidae.[1]

Genera within the family Cochliopidae include:

subfamily Cochliopinae

subfamily Littoridininae

subfamily Semisalsinae - there are three genera in the subfamily Semisalsinae[8]

subfamily ? (either Cochliopinae or Littoridininae)
