Doridoidea, commonly known as dorid nudibranchs (and previously known as the taxon Cryptobranchia), are a taxonomic superfamily of medium to large, shell-less sea slugs, marine gastropod mollusks in the clade Doridacea, included in the clade Nudibranchia.

Etymology

The word "Doridoidea" comes from the generic name Doris, which was in turn copied from the name of the sea nymph, Doris, in Greek mythology.

According to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), families within the superfamily Doridoidea include:

Changes later than 2005

The family Cadlinidae Bergh, 1891 was considered a synonym of the Chromodorididae. Research by R.F. Johnson in 2011 [2] has shown that Cadlina does not belong to the family Chromodorididae. She has therefore brought back the name Cadlinidae from synonymy with Chromodorididae. The chromodorid nudibranchs without Cadlina are now monophyletic and turn out to be a possible sister to the Actinocyclidae

Cryptobranch dorid nudibranchs

Cryptobranch dorid nudibranchs (previously known as the taxon Cryptobranchia), are nudibranch sea slugs within the clade Doridacea. These slugs are called "cryptobranch," meaning "hidden gill", because they are able to retract their gills into a gill pocket, in contrast to nudibranchs in the traditional group phanerobranchs (or Phanerobranchia), which taxon is probably paraphyletic (in other words, composed of more than one evolutionary lineage). [3]

A. Valdés distinguishes two major clades within the Cryptobranchia: the dorids that have no radula (the Porostomata); and those with a radula (the Labiostomata). The Labiostomata include the monophyletic families: Actinocyclidae, Chromodorididae, Dorididae and Discodorididae. [4]

The cryptobranchs include the following genera that are regarded as valid:

Dorididae family of molluscs

Sea lemon is a loosely applied common name for a group of medium-sized to large shell-less colorful sea slugs or nudibranchs, specifically dorid nudibranchs in the taxonomic family Dorididae and other closely related families. These are marine gastropod mollusks.

Chromodorididae family of molluscs

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.

<i>Cadlina</i> genus of molluscs

Cadlina is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks historically classified in the family Chromodorididae. Recent research by R.F. Johnson in 2011 has shown that Cadlina does not belong to the family Chromodorididae. She has therefore brought back the name Cadlinidae from synonymy with Chromodorididae. The family Cadlinidae also includes the genus AldisaBergh, 1878.

Discodorididae is a taxonomic family of sea slugs, specifically dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea.

Euctenidiacea suborder of molluscs

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.

Platydoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae. These nudibranchs are large and often brightly coloured, but normally live concealed beneath rocks or loose coral, feeding on sponges. During the night they become more active, searching for new food sources or mates. Many species were described in the 19th century and a revision in 2002 added six new species.
