Architaenioglossa

Viviparidae, commonly called river snails, are a family of freshwater snails with gills and a protective lid (operculum). Their family tree is complex, and genetic evidence suggesting some species in this family don't fit neatly into traditional groups. These snails are native lakes and rivers across Europe, Asia, and parts of North America. Some, like Cipangopaludina japonica, have become invasive thanks to their ability to adapt.thumb|Intact image of Viviparus contectus from Netherlands thumb|Empty shells of Viviparidae Bellamya unicolor thumb|Viviparidae image ==Distribution== This family

Architaenioglossa is a taxonomic group of snails which have gills and often an operculum. They are primarily land and freshwater gastropod mollusks within the clade Caenogastropoda.

Cyclophoroidea is a superfamily of land snails with an operculum, terrestrial gastropods within the order Architaenioglossa, that belongs to the subclass Caenogastropoda. Approximately 3,675 cyclophoroid species were known as of 2024, making them the second-most diverse clade of land snails after Stylommatophora.

Ampullarioidea is a taxonomic superfamily of freshwater snails, aquatic gastropod mollusks within the informal group Architaenioglossa, which belongs to the clade Caenogastropoda (unassigned).
