Gastropods, commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Sea snails are slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell.
Vertiginidae, common name the whorl snails, is a family of minute, air-breathing land snails, terrestrial pulmonate gastropod molluscs or micromollusks in the superfamily Pupilloidea.
Achatinellidae is a family of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Pupilloidea.
Assimineidae is a family of minute snails, also known as palmleaf snails, with an operculum, gastropod mollusks or micromollusks in the superfamily Rissoidae. Many of these very small snails live in intermediate habitats, being amphibious between saltwater and land; others live in freshwater.
Turritellidae, with the common name "tower shells" or "tower snails", is a taxonomic family of small- to medium-sized sea snails, marine gastropod molluscs in the Sorbeoconcha clade.
The Littorinidae are a taxonomic family of over 200 species of sea snails, marine gastropod molluscs in the clade Littorinimorpha, commonly known as periwinkles and found worldwide.
Liniaxis is a genus of medium-sized sea snails, marine gastropod mollusks in the subfamily Coralliophilinae, the coral snails, within the family Muricidae, the murex snails and rock snails.
Ampullinidae are a mostly extinct taxonomic family of sea snails, marine gastropod molluscs in the clade Caenogastropoda.
Cymbulioidea is a taxonomic superfamily of pelagic "sea butterflies", one group of swimming sea snails. They are holoplanktonic opisthobranch gastropod molluscs in the clade Thecosomata.
Trajanellidae is an extinct family of fossil sea snails, marine gastropod molluscs in the clade Caenogastropoda.
Conus collisus, common name the stigmatic cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.
Conorbis is an extinct genus of sea snails, marine gastropod mollusks in the family Conorbidae.
Granuliterebra is a genus of sea snails, marine gastropod molluscs in the family Terebridae, the auger snails.
Conasprella ichinoseana is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.
Ampullinopsis is an extinct taxonomic genus of deep-water sea snails, marine gastropod molluscs in the clade Sorbeoconcha. These sea snails were epifaunal grazers. Sea snails of this genus lived from Paleocene epoch to Miocene epoch.
Holopea is an extinct genus of fossil sea snails, Paleozoic gastropod mollusks in the family Holopeidae.
Conus is a genus of venomous and predatory sea snails, or cone snails, marine gastropod mollusks in the family Conidae. Prior to 2009, it included all cone snail species but is now more precisely defined, as are other cone snail genera.
Purpuroidea is an extinct genus of sea snails, marine gastropod molluscs in the clade Littorinimorpha.
