Tritonioidea is a superfamily of sea slugs, nudibranchs, shell-less marine gastropod mollusks in the Suborder Cladobranchia. [1]
Tritonioidea was the only superfamily in the clade Dendronotida. The taxonomy of Bouchet & Rocroi for the clade Dendronotida was largely based on the classification established by Boss in 1982, [2] who in turn based his conclusions on the study by Odhner in 1968. [3]
The study of Wägele and Willan, published in 2000, [4] concluded that Dendronotida is monophyletic, although this monophyly had been questioned, based on the wide variety in sperm morphology, in a paper by Healy & Willan in 1991. [5]
Taxonomy in the Superfamily Tritonoidea is as follows: [1]
Superfamily Tritonioidea
Families currently accepted as synonyms:
Nudibranchs are a group of soft-bodied, marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown," "marigold," "splendid," "dancer," "dragon," or "sea rabbit." Currently, about 3,000 valid species of nudibranchs are known.
Orthogastropoda was a major taxonomic grouping of snails and slugs, an extremely large subclass within the huge class Gastropoda according to the older taxonomy of the Gastropoda.
Doridoidea, commonly known as dorid nudibranchs, are a taxonomic superfamily of medium to large, shell-less sea slugs, marine gastropod mollusks in the clade Doridacea, included in the clade Nudibranchia.
Doridoxidae, commonly known as doridoxid nudibranchs, are a small, enigmatic taxonomic family of shell-less sea slugs, marine gastropod molluscs in the clade Cladobranchia within the clade Nudibranchia.
The Polyceridae are a taxonomic family of sea slugs, dorid nudibranchs, marine gastropod mollusks within the superfamily Polyceroidea.
Arminoidea is a superfamily of small sea slugs, marine gastropod molluscs in the clade Nudibranchia.
Dendronotoidea was a taxonomic superfamily of small colorful sea slugs or nudibranchs, aeolid nudibranchs.
The Chromodorididae, or chromodorids, are a taxonomic family of colourful, sea slugs; dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea. “Chromodorid nudibranchs are among the most gorgeously coloured of all animals.” The over 360 described species are primarily found in tropical and subtropical waters, as members of coral reef communities, specifically associated with their sponge prey. The chromodorids are the most speciose family of opisthobranchs. They range in size from <10mm to over 30 cm, although most species are approximately 15–30 mm in size.
Plakobranchidae is a family of sea slugs, marine opistobranch gastropod mollusks in the superfamily Plakobranchoidea. They superficially resemble nudibranchs but they are sacoglossans, members of the clade Sacoglossa within the Opisthobranchia.
The Tritoniidae are a taxonomic family of dendronotid nudibranchs, shell-less marine gastropod molluscs. This family includes some of the largest known nudibranchs, with the NE Atlantic species Tritonia hombergii reaching 20 cm in length.
Arminidae is a family of sea slugs, marine gastropod mollusks in the superfamily Arminoidea.
Scyllaeidae is a taxonomic family of sea slugs, nudibranchs, marine gastropod mollusks in the superfamily Tritonioidea.
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.
Apogastropoda was previously used as a major taxonomic grouping of sea snails, marine gastropod molluscs. This infraclass mostly consisted of marine limpets and operculate snails. At least 20,000 species were considered to exist within the two clades that were included, Heterobranchia and Caenogastropoda.
The Euctenidiacea, common name dorid nudibranchs, are a taxonomic suborder of sea snails or slugs, marine gastropod molluscs in the order Nudibranchia. Bouchet & Rocroi (2005) rejected the name Anthobranchia on the grounds that it also included Onchidium at the time of original publication. Doridina is equivalent and used in the latest classification.
The Dexiarchia are a suborder of sea slugs, shell-less marine gastropod molluscs in the order Nudibranchia. This classification is based on the study by Schrödl et al., published in 2001, who recognized within this clade two clades Pseudoeuctenidiacea and Cladobranchia.
The Cladobranchia are a taxonomic clade of nudibranchs, sea slugs, marine gastropod molluscs in the clade Dexiarchia.
The Aeolidida is a taxonomic clade of sea slugs, specifically aeolid nudibranchs, marine gastropod molluscs in the clade Cladobranchia. They are distinguished from other nudibranchs by their possession of cerata containing cnidosacs.
Curnonidae is a small family of sea slugs, nudibranchs, shell-less marine gastropod molluscs, in the clade Euthyneura.
Tochuina is a genus of sea slugs, tritonid nudibranchs, marine gastropod mollusks in the family Tritoniidae.
