It contains only one superfamily, Neomphaloidea McLean, 1981.
Gastropods, commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are gastropods, i.e. they are sea snails that, over evolutionary time, have either entirely lost their shells or have seemingly lost their shells due to having a significantly reduced or internal shell. The name "sea slug" is often applied to nudibranchs and a paraphyletic set of other marine gastropods without apparent shells.
Caenogastropoda is a taxonomic subclass of molluscs in the class Gastropoda. It is a large diverse group which are mostly sea snails and other marine gastropod mollusks, but also includes some freshwater snails and some land snails. The subclass is the most diverse and ecologically successful of the gastropods.
Hypsogastropoda is a clade containing marine gastropods within the clade Caenogastropoda.
Volutoidea is a taxonomic superfamily of predatory sea snails, marine gastropod mollusks in the clade Neogastropoda.
Neomphalidae is a family of sea snails or limpets, specifically deep sea hydrothermal vent limpets. This family was included in the Vetigastropoda, which is a clade according to the Bouchet & Rocroi, 2005. It is now included in the clade Neomphalina.
Neomphaloidea is a superfamily of deep-sea snails or limpets, marine gastropod mollusks. Neomphaloidea is the only superfamily in the order Neomphalida.
Neritidae, common name the nerites, is a taxonomic family of small to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum. The family Neritidae includes marine genera such as Nerita, marine and freshwater genera such as Neritina, and freshwater and brackish water genera such as Theodoxus.
Sagdoidea is a superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the infraorder Helicoidei of the suborder Helicina.
The Rhytidoidea are a superfamily of air-breathing land snails and slugs, terrestrial gastropod mollusks in the suborder Helicina.
Seguenzioidea is a superfamily of sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Succineoidea is a taxonomic superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the suborder Helicina.
Oxynooidea is a superfamily of small sea snails, bubble snails and bivalved gastropods, marine gastropod mollusks within the superorder Sacoglossa.
Mathildoidea is a superfamily of sea snails, marine gastropod mollusks in the informal group Lower Heterobranchia.
The Personidae are a family of sea snails, marine gastropod molluscs in the order Littorinimorpha.
