The Ohio pebblesnail (Somatogyrus integra) is a species of very small freshwater snail with an operculum. It is an aquatic gastropod mollusc in the family Lithoglyphidae . Distribution
Helicidae is a large, diverse family of western Palaearctic, medium to large-sized, air-breathing land snails, sometimes called the "typical snails."It includes some of the largest European land snails, several species are common in anthropogenic habitats, and some became invasive on other continents.
The young snails are kept in the nursery for about 6 weeks, and then moved to a separate pen, as young snails do best if kept with other snails of similar size. Eight hours of daylight is optimal for young snails. Baby snails are fed on tender lettuce leaves (Boston type, but head type is probably also good). Cannibalism by hatchlings
The phylogeny (evolutionary "family tree") of molluscs is a controversial subject. In addition to the debates about whether Kimberella and any of the " halwaxiids " were molluscs or closely related to molluscs, [ 5 ] [ 6 ] [ 8 ] [ 9 ] debates arise about the relationships between the classes of living molluscs.

Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum. [2] Species within this superfamily have nacre as the inner shell layer. The families within this superfamily include the Trochidae, the top snails. This superfamily is the largest vetigastropodan superfamily, containing more than 2,000 species.
Architectonicidae, common name the staircase shells or sundials, are a family of sea snails, marine gastropod mollusks in the informal group "Lower Heterobranchia" (= Allogastropoda) of the clade Heterobranchia. The extinct families † Amphitomariidae Bandel, 1994 and † Cassianaxidae Bandel, 1996 belong to the same superfamily.
The family Pomatiidae is a taxonomic family of small operculate land snails, terrestrial gastropod mollusks that can be found over the warmer parts of the Old World. In the older literature, this family is designated as Pomatiasidae. This family is a lineage closely related to the Littorinidae (periwinkles) common in coastal habitat. They have ...
Littorinoidea are a superfamily of both sea snails and land snails which have a gill and an operculum, terrestrial and marine gastropod mollusks in the clade Littorinimorpha. [2]The terrestrial family within this group, the Pomatiidae, are sometimes called "land winkles" [3] because the group originated in the sea and the closely related family Littorinidae are known as "winkles".
