Non-Marine Gastropod Mollusks of the Clade Neritomorpha

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.  All extant members of this clade are in the subclade Cycloneritimorpha.

 

Ecology

Terrestrial species are found in four families.  They are indicated in green in the list below.  Freshwater species are found in one family, the Neritidae in the superfamily Neritoidea.  They are indicated in blue in the list below.  Exclusively marine families are in black.
