Nudibranchs
Nudibranchia
Nudibranchs () are a group of soft-bodied marine gastropod molluscs, belonging to the order Nudibranchia, 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". About 3,000 species of nudibranchs are known.
The word nudibranch comes from the Latin nudus 'naked' and the Ancient Greek βράγχια (bránkhia) 'gills'.
