Nudibranchs belong to the order Nudibranchia, a group of soft-bodied marine gastropod molluscs that 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", and "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.
Melibe viridis is a species of sea slug, a nudibranch, a marine gastropod mollusk in the family Tethydidae.
Scyllaeidae is a taxonomic family of sea slugs, nudibranchs, marine gastropod mollusks in the superfamily Dendronotoidea.
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.
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.
Dendronotus is a genus of sea slugs, nudibranchs, marine gastropod molluscs in the superfamily Tritonioidea.
Glaucus is a genus of small blue pelagic sea slugs. They are aeolid nudibranchs, ranging in size from 20 to 40 mm. They feed on colonial cnidarians such as Portuguese man o' wars, blue buttons, and purple sails. They can produce painful and potentially dangerous stings when handled, as they store the venomous nematocysts of their prey. Glaucus is the only genus in the family Glaucidae. It includes five species.
Goniobranchus roboi, common name the tooth-edged chromodoris, is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae. This species was transferred from Chromodoris to Goniobranchus in 2012.
Goniobranchus verrieri is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.
Notobryon is a genus of nudibranchs. They are marine gastropod molluscs in the family Scyllaeidae.
Felimida galexorum is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.
Cadlina abyssicola is a species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Cadlinidae.
Scyllaea is a genus of nudibranchs. They are marine gastropod molluscs in the family Scyllaeidae.
Scyllaea pelagica, common name the sargassum nudibranch, is a species of nudibranch, a marine gastropod mollusc in the family Scyllaeidae. This species lives among floating seaweed in the world's oceans, feeding on hydroids.
Corambe steinbergae is a species of sea slug, an Eastern Pacific Ocean nudibranch, a marine, opisthobranch gastropod mollusk in the family Corambidae.
Notobryon clavigerum is a species of sea slug, a nudibranch, a marine gastropod mollusk in the family Scyllaeidae.
Crosslandia daedali is a species of sea slug within the family Scyllaeidae, found in subtropical waters in the Eastern Central Pacific Ocean in Mexico and Costa Rica. It lives in benthic environments, usually on algae within the genus Padina where it grazes on small hydroids.
