Retusidae is a family of very small sea snails, barrel-bubble snails, marine opisthobranch gastropod mollusks. These are headshield slugs, in the superfamily Bulloidea. [1]
Genera within the family Retusidae include:
The order Cephalaspidea, also known as the headshield slugs and bubble snails, is a major taxon of sea slugs and bubble snails, marine gastropod mollusks within the larger clade Euopisthobranchia. Bubble shells is another common name for these families of marine gastropods, some of which have thin bubble-like shells. This clade contains more than 600 species.
Bulla is a genus of medium to large hermaphrodite sea snails, shelled marine opisthobranch gastropod molluscs. These herbivorous snails are in the suborder Cephalaspidea, headshield slugs, and the order Opisthobranchia.
Haminoeidae, commonly known as the haminoeid bubble snail family, is a taxonomic family of sea snails, marine opisthobranch gastropod mollusks in the superfamily Haminoeoidea.
Bulimulidae is a taxonomic family of medium-sized to large, air-breathing, tropical and sub-tropical land snails, terrestrial pulmonate gastropod molluscs in the superfamily Orthalicoidea.
Fissurellidae, common name the keyhole limpets and slit limpets, is a taxonomic family of small to medium-sized limpet-like sea snails, marine gastropod molluscs in the clade Vetigastropoda.
Bulloidea is a superfamily of sea snails, or bubble snails, marine gastropod mollusks.
The Ranellidae, common name the triton shells or tritons, are a taxonomic family of small to very large predatory sea snails, marine gastropod mollusks in the order Littorinimorpha.
Clausiliidae, also known by the common name door snails, is a taxonomic family of small, very elongate, mostly left-handed, air-breathing land snails, sinistral terrestrial pulmonate gastropod mollusks.
Teinostoma is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Teinostomatidae.
Partulidae is a family of air-breathing land snails, terrestrial gastropod mollusks in the superfamily Pupilloidea.
Camaenidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea, the typical snails and their allies. This is one of the most diverse families in the clade Stylommatophora.
Naticidae, common name moon snails or necklace shells, is a family of medium to large-sized predatory sea snails, marine gastropod molluscs in the clade Littorinimorpha. The shells of the species in this family are mostly globular in shape.
Tornidae is a family of very small and minute sea snails with an operculum, marine gastropod mollusks in the clade Littorinimorpha. This family used to be known as the Vitrinellidae. Iredale has shown that the family Adeorbidae Monterosato, 1884 should be called Tornidae
Xanthonychidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
Cylichna is a genus of sea snails or bubble snails, marine gastropod molluscs in the family Cylichnidae, the "chalice bubble snails".
Vanikoridae is a family of minute to medium-sized sea snails, marine gastropod molluscs in the superfamily Vanikoroidea.
Haminoea is a genus of medium-sized sea snails or bubble snails, marine opisthobranch gastropod molluscs in the family Haminoeidae, the haminoea bubble snails, part of the clade Cephalaspidea, the headshield slugs and bubble snails.
Retusa truncatula is a species of very small head-shield sea snail or barrel-bubble snail, a marine gastropod mollusc in the family Retusidae
Retusa is a genus of very small head-shield sea snails or barrel-bubble snails, marine gastropod molluscs in the family Retusidae.
The Zeidorinae, common name keyhole limpets and slit limpets, is a taxonomic subfamily of limpet-like sea snails, marine gastropod molluscs in the family Fissurellidae, the keyhole limpets and slit limpets.
