Feeding habits, diets and trophic relationships among three demersal sharks (Galeus melastomus Rafinesque, 1810; Etmopterus spinax (Linnaeus, 1758); and Scyliorhinus canicula (Linnaeus, 1758)) from the Porcupine Bank, Northeast Atlantic were studied. The stomach content analysis revealed differences between the diet of the three species, with a clear preference for benthonic preys in the case of S. canicula, and benthopelagic preys in the case of E. spinax and G. melastomus. The results of this study provide new knowledge about the ecological role of these species in the Porcupine Bank and will be of vital importance for their management and conservation of these species.
