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.
Rostanga is a genus of sea slugs in the family Discodorididae. Some sources, such as The Sea Slug Forum still classify Rostanga in the family Dorididae.
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.
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.
Rostanga pulchra is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Discodorididae.
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.
Limacia cockerelli is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Polyceridae.
Discodorididae is a taxonomic family of sea slugs, specifically dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea.
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 Facelinidae are a taxonomic family of colorful sea slugs. These are specifically aeolid nudibranchs. They are marine gastropod molluscs.
Taringa is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Mexichromis is a genus of colourful sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae. Current synonymy follows a revision of Chromodorididae which used molecular phylogeny.
Paradoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Thordisa is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Phyllidiopsis is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs and is the largest genus within the family Phyllidiidae.
Halgerda terramtuentis is a species of sea slug, a dorid nudibranch, shell-less marine gastropod mollusks in the family Discodorididae.
Halgerda tessellata is a species of sea slug, a dorid nudibranch, shell-less marine gastropod mollusks in the family Discodorididae.
Felimare californiensis, common name the California blue dorid, is a species of colourful sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae that eats dysideid sponges.
Acanthodoris caerulescens is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Onchidorididae.
