The common inshore Nudibranch, Onchidoris fusca (Muller), has been observed feeding on barnacles, and the feeding behaviour and the extent of predation followed. The dorid effects entry by rupture and downward displacement of the operculum, and feeds only on the soft parts of the barnacle. It is probable that ingestion takes place largely by suction, involving the action of the buccal crop, the presence of which in this and certain other dorids is associated with a much reduced radula. The possibility that the diet of O. fusca is restricted to barnacles is considered.
