Non-Marine Gastropod Mollusks of the Clade Caenogastropoda

This is one of the six major gastropod lineages and contains a large number of terrestrial species and a few freshwater and brackish water species.  All have an operculum.  There are three major subclades: the Architaenioglossa, the Sorbeoconcha and the Hypogastropoda.  The relationships among the three subgroups are in dispute. The hypothesis of Bouchet & Rocroi (2005) is shown below. 



Terrestrial species are found in two of the three main subclades, Architaenioglossa, and Hypogastropoda.  Families with terrestrial species are in green in the list below.  A few species in the third subclade, Sorbeoconcha, in the family Potamididae, live in brackish water, mudflats, and even in mangrove trees. Members of the family Assimineidae (Hypogastropoda, Littorinimorpha) are mostly aquatic, but live in saltwater, freshwater and are terrestrial.  These species can be considered amphibious.  Families with amphibious species are in red in the list below.  Freshwater members of the Caeonogastropoda are found in all three major subclades.  Families with freshwater species are in blue in the list below. Families in black are exclusively marine.  Families with Illinois species are noted.
