Rissooidea, originally named Rissoacea by Grey, 1847, is a large taxonomic superfamily of small and minute saltwater, brackish water, freshwater, and semi-terrestrial snails which have gills and an operculum. The gastropod mollusks in this superfamily are mostly marine, but as can be seen from the following list, the superfamily also includes some freshwater, brackish water, and semi-terrestrial families and genera.
