The diets, morphological features and habitats of 258 specimens of the three inshore fish species Notothenia coriiceps, N. macrocephala and Harpagifer georgianus from Marion Island are descriptionbed and compared. Correspondence analysis of the three diets shows the existence of three clearly defined feeding niches despite the occurrence of some common prey species. Inter- and intraspecific similarities and differences in the diets of small and large size classes of each species are also displayed by correspondence analysis. Size-limited predation by N.coriiceps of the limpet Nacella delesserti is descriptionbed. Differences in the habitats occupied by the fish appear to be important in determining the species composition of their diets.
