The superfamily Limacinoidea is a taxonomic group of small floating sea snails, pelagic marine opisthobranch gastropod mollusks. [1]
These families previously belonged to the superfamily Cavolinioidea.
Neogastropoda is a clade of sea snails, both freshwater and marine gastropod molluscs.
The Limacinidae are a family of small sea snails, pteropods, pelagic marine gastropod mollusks in the clade Thecosomata.
The superfamily Cavolinioidea is the most speciose group of sea butterflies. Sea butterflies (thecosomata) are pelagic marine gastropods, so called because they swim by flapping their wing-like parapodia.
Volutoidea is a taxonomic superfamily of predatory sea snails, marine gastropod mollusks in the clade Neogastropoda.
Rissooidea, originally named Rissoacea by Gray, 1847, is a taxonomic superfamily of small and minute marine snails, belonging to the clade Littorinimorpha.
Conoidea is a superfamily of predatory sea snails, marine gastropod mollusks within the suborder Hypsogastropoda. This superfamily is a very large group of marine mollusks, estimated at about 340 recent valid genera and subgenera, and considered by one authority to contain 4,000 named living species.
Cypraeoidea, the cowries and cowry allies, is a superfamily of sea snails, marine gastropods included in the clade Littorinimorpha. This superfamily had been called Cypraeacea and was named by Rafinesque in 1815.
Buccinoidea is a taxonomic superfamily of very small to large predatory sea snails, marine gastropod mollusks.
Aeolidioidea is a superfamily of sea slugs, the aeolid nudibranchs. They are marine gastropod molluscs in the suborder Cladobranchia.
Calliostomatidae is a family of sea snails within the superfamily Trochoidea and the clade Vetigastropoda.
Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum. 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.
Limapontioidea are a superseded superfamily of sea slugs, marine gastropod mollusks within the superorder Sacoglossa.
Plakobranchoidea is a taxonomic superfamily of sea slugs, marine gastropod mollusks within the superorder Sacoglossa.
Clavatulidae is a taxonomic family of sea snails, marine gastropod mollusks in the superfamily Conoidea. The family is not well differentiated morphologically.
The family Cavoliniidae is a taxonomic group of small floating sea snails, pelagic marine opisthobranch gastropod mollusks.
Clathurellidae is a monophyletic family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.
Mitromorphidae is a monophyletic family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.
Margaritidae is a family of small sea snails, marine gastropod mollusks in the superfamily Trochoidea.
Truncatelloidea is a superfamily of snails, gastropod mollusks in the clade Caenogastropoda.
Trochida is an order of small to very large vetigastropod, Recent and extinct sea snails with gills and an operculum.
