This small animal (maximum 11 mm) can hardly be confused with any other species. The distinct yellow border on its dorsal side is easily recognized. Often there are red or brown blotches on the mantle. The short, pointed cerata are translucent white.


It is often found on rocky locations covered by a layer of mud or fine sand. It feeds on Bryozoans.


It is abundant in the western Mediterranean, but has been reported along the Atlantic coasts of Europe, as far north as Trøndelag, Norway.
