Description
Thuridilla is a genus of sacoglossan sea slugs (sap-sucking slugs) in the family Plakobranchidae. Wikipedia lists 24 species. Most live on tropical coral reefs in the Indo-Pacific (such as T. gracilis in the western Pacific), and one, T. hopei, is described from the Mediterranean. Like other sacoglossans they feed on algae.
Identification
Small, elongate, colourful sacoglossans, 10 to 25 mm long, with parapodia along the sides and prominent smooth rhinophores. Warning colours are typical: a dark or deep green body with 8 to 10 fine white longitudinal lines, sometimes blue spots, and orange edges on the parapodia, head and rhinophores (for example T. gracilis). Colour varies between and within populations.
