The general behaviour and feeding of the tube dwelling coelenterate Cerianthus lloydi was investigated in situ in a shallow sandy bay by means of underwater television. Continuous field and laboratory observations failed to show the existence of any diurnal rhythmic activity. Analysis of the stomach content of 17 individuals revealed a carnivorous diet consisting of epibenthic invertebrates mostly crustaceans as well as smaller components such as meiofaunal organisms from the sediments surrounding the anemone tube. Predation effect on the abundant meiofaunal community is examined and the importance of the meiofaunal organisms in the diet of Cerianthus and other species is reviewed. The position of Cerianthus in a benthic food chain is briefly discussed.
