Abstract: This study describes the feeding responses of Balanus glandula, with particular reference to food particle characteristics which evoke those responses as follows: 1) Captorial feeding is induced by tactile stimulation. This stimulation is provided by any particle within a size range of approximately 20mu to 400mu. 2) An endogenous regulation of captorial feeding maintained feeding activity in those barnacles which have recently fed. 3) no selection of particles corresponding to nutritive values occurs during filtration or ingestion. 4) These conclusions are discussed in relation to the gut contents of barnacles recently collected in the intertidal.
