Nudibranchs (/ˈnjuːdɪbræŋk/[2]) are a group of soft-bodied marine gastropod molluscs, belonging to the order Nudibranchia, that shed their shells after their larval stage.[3] 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[4] "sea rabbit".[5] About 3,000 species of nudibranchs are known.[6]
The word nudibranch comes from the Latin nudus 'naked' and the Ancient Greek βράγχια (bránkhia) 'gills'.
Nudibranchs are often casually called sea slugs, as they are a family of opisthobranchs (sea slugs), within the phylum Mollusca (molluscs), but many sea slugs belong to several taxonomic groups that are not closely related to nudibranchs. A number of these other sea slugs, such as the photosynthetic Sacoglossa and the colourful Aglajidae, are often confused with nudibranchs.
