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

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

2005 taxonomy

The family Cochliopidae consists of 3 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):[2]

  • Cochliopinae Tryon, 1866 - synonyms: Mexithaumatinae D. W. Taylor, 1966, Paludiscalinae D. W. Taylor, 1966
