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.

Families

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

Actinocyclidae ^{O'Donoghue, 1929}
Chromodorididae ^{Bergh, 1891}
Discodorididae ^{Bergh, 1891}
Dorididae ^{Rafinesque, 1815}

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

Currently Recognized Families

Actinocyclidae ^{O'Donoghue, 1929}
Cadlinidae ^{Bergh, 1891}
Chromodorididae ^{Bergh, 1891}
Discodorididae ^{Bergh, 1891}
Dorididae ^{Rafinesque, 1815}

Cadlina luteomarginata of Cadlinidae
Goniobranchus geminus of Chromodorididae
Diaulula nobilis of Discodorididae
Doris montereyensis of Dorididae

The next families are considered synonyms. But these names can still be found in many publications and on the internet.

Aldisidae ^{Odhner, 1939} - synonym of Cadlinidae
Archidorididae ^{Bergh, 1891} - synonym of Dorididae
Asteronotidae ^{Thiele, 1931} - synonym of Discodorididae
Baptodorididae ^{Odhner, 1926} - synonym of Discodorididae
Conualeviidae ^{Collier & Farmer, 1964} - synonym of Dorididae
Geitodorididae ^{Odhner, 1968} - synonym of Discodorididae
Halgerdidae ^{Odhner, 1926} - synonym of Discodorididae
Homoiodorididae ^{Bergh, 1882} -synonym of Dorididae and Dendrodorididae
Kentrodorididae ^{Bergh, 1891} - synonym of Discodorididae
Platydorididae ^{Bergh, 1891} - synonym of Discodorididae
Rostangidae ^{Pruvot-Fol, 1951} - synonym of Discodorididae

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).

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.

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

Doris Linnaeus, 1758
Asteronotus Ehrenberg, 1831
Atagema J. E. Gray, 1850
Jorunna Bergh, 1876
Discodoris Bergh, 1877
