Description

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

2005 taxonomy

The family Cochliopidae consists of 3 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): * Cochliopinae Tryon, 1866 - synonyms: Mexithaumatinae D. W. Taylor, 1966, Paludiscalinae D. W. Taylor, 1966 * Littoridininae Thiele, 1928 * Semisalsinae Guiusti & Pezzoli, 1980 - synonym: Heleobiini Bernasconi, 1991

Genera

Liu et al. (2001) have recognized 34 genera with more than 260 species within the subfamily Cochliopinae. Strong et al. (2008)Strong E. E., Gargominy O., Ponder W. F. & Bouchet P. (2008). "Global Diversity of Gastropods (Gastropoda; Mollusca) in Freshwater". ''
