Philinoidea is a taxonomic superfamily of sea slugs, specifically headshield slugs, marine gastropod mollusks in the order Cephalaspidea. [1]
The species in the Superfamily Philinoidea are generally small animals that have an internal or external shell, and a covered gill. Unlike some related forms, the visceral mass is not sharply set off from the rest of the body. [2]
According to the latest taxonomy, the following families are recognised in the Superfamily Philinoidea: [1]
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.
Diaphanoidea is a taxonomic superfamily of small sea snails, marine opisthobranch gastropod mollusks or micromollusks in the Cephalaspidea, the headshield slugs and bubble snails.
Haminoeoidea is a taxonomic superfamily of small sea snails or bubble shells, marine opisthobranch gastropod mollusks in the clade Cephalaspidea, the headshield slugs and bubble snails.
Haminoeidae, commonly known as the haminoeid bubble snail family, is a taxonomic family of sea snails, marine opisthobranch gastropod mollusks in the superfamily Haminoeoidea.
Aglajidae is a family of often colorful, medium-sized, sea slugs, marine opisthobranch gastropod mollusks. These are not nudibranchs; instead they are headshield slugs, in the clade Cephalaspidea.
Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.
Bulloidea is a superfamily of sea snails, or bubble snails, marine gastropod mollusks.
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.
Philinidae is a family of medium-sized sea slugs, marine opisthobranch gastropod mollusks. These are headshield slugs, in the order Cephalaspidea.
Cylichnidae, common name the "chalice bubble snails" or "canoe bubble snails" is a family of sea snails or bubble snails, marine gastropod mollusks in the superfamily Cylichnoidea.
The taxonomy of the Gastropoda, as revised by Winston Ponder and David R. Lindberg in 1997, is an older taxonomy of the class Gastropoda, the class of molluscs consisting of all snails and slugs. The full name of the work in which this taxonomy was published is Towards a phylogeny of gastropod molluscs: an analysis using morphological characters.
Runcinoidea is a taxonomic superfamily or a clade Runcinaecea of sea slugs, marine gastropod mollusks in the order Runcinida
Scaphandridae is a family of sea snails, marine gastropod mollusks in the superfamily Philinoidea.
Rhizoridae is a family of very small sea snails, barrel-bubble snails, marine opisthobranch gastropod molluscs. These are headshield slugs, in the superfamily Bulloidea.
Tornatinidae is a family of very small sea snails, barrel-bubble snails, marine opisthobranch gastropod molluscs. These are headshield slugs, in the superfamily Bulloidea.
Smaragdinella 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.
Cylichnium is a genus of very small sea snails, unassigned in a family in the order Cephalaspidea.
Laonidae is a family of small marine snails belonging to the superfamily Philinoidea, though Laonidae and Philinoidea are genetically distinct. They are monophyletic, meaning they are developed from a single ancestor. Laonidae also has the synonymised name Laoninae, which is largely unaccepted in the modern day scientific community. The name Laoninae is introduced by Alice Pruvot-Fol who proposes it as the subfamily to the genea Loana, A.Adams 1865.
Alacuppidae is a family of often colorful, medium-sized, sea slugs, marine opisthobranch gastropod mollusks.
Phanerophthalmus 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.
