Among 1557 prey items isolated from the stomachs of bull ray specimens, gastropods represented the overwhelming majority (93.8%). Within gastropods, Aporrhais pespelecani was the dominant species, followed by Gibbula magus and Bolinus brandaris – all characteristic elements of the biocoenosis of the muddy detritic bottom. We observed differences in prey structure between juveniles and adults, as well as sexes. Among fishes that proved to be particularly important in terms of biomass, the majority of prey items consisted of small pelagic fish, including pilchard (Sardina pilchardus) and horse mackerel (Trachurus sp.). This paper contributes new data on the feeding ecology of a lesser known and critically endangered batoid speciesRaziskava poroča o osnovnih podatkih o prehranjevalnih navadah kljunatega morskega goloba Aetomylaeus bovinus (Geoffroy Saint-Hilaire, 1817) v Beneškem zalivu. Med 1557 primerki plena, izoliranimi iz želodcev, so veliko večino predstavljali polži (93,8 %). Med njimi je prevladovala vrsta Aporrhais pespelecani, sledili sta ji Gibbula magus in Bolinus brandaris. Te vrste so značilni elementi biocenoze muljastega detritnega dna. Opazili smo razlike v strukturi plena med mladimi in odraslimi primerki ter med spoloma. Med ribami, ki so se izkazale za pomembne predvsem z vidika biomase, so največ plena predstavljale male pelagične ribe, kot sta sardela (Sardina pilchardus) in šur (Trachurus sp.).
