Anthobranchia
Doridina

The Euctenidiacea, common name dorid nudibranchs, are a taxonomic suborder of sea snails or slugs, marine gastropod molluscs in the order Nudibranchia. [2] Bouchet & Rocroi (2005) rejected the name Anthobranchia on the grounds that it also included Onchidium at the time of original publication. Doridina [3] is equivalent and used in the latest classification. [4]

A morphological phylogenetic study, published in 2000, by Wägele & Willan showed that the subclade Gnathodoridacea (= Bathydoridoidea) and the subclade Doridacea (= Phanerobranchia + Cryptobranchia + Porostomata) each form a monophyletic group. [5]

In a later study, published in 2002, A. Valdés concluded that the superfamilies Doridoidea and Phyllidioidea (called by him Cryptobranchia + Porostomata) formed a clade. He expanded the usage of Cryptobranchia to encompass the whole subclade Doridacea. [6] This move was not followed in the taxonomy of Bouchet and Rocroi.

Nudibranch order of molluscs

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.

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.
