Resumo

This research has been done on the basis of samples obtained at depths between 21 and 63m by trawling in Golfo Triste. The stomach content of 153 specimens of Tethyaster vestitus and 981 specimens of Astiopecten riensis were analyzed. A.riensis seems to be an important element within the trophic structure of the community under study, constituting the second and third level of consumers. T.verstitus is, within the above-mentioned community one of the rare constitiuents of the 4th level consumers despite the fact that it takes part in the 3rd level as well.
