The aim of this study was the investigation of trophic interactions in intertidal food webs with focus on trophic links between rocky intertidal predators of genus Nucella and their prey (mussels and barnacles). Foraging strategy of naturally feeding dogwhelL• was observed in the field. The pattern that dogwhelks tended to prey mostly on Mytilus californianus rather than on Mytilus trossulus and barnacles was clearly seen. Complete diet records were obtained for 16 dogwhelL• fed on Mytilus
