The diet of the milk shark, Rhizoprionodon acutus, from the Senegalese coast was investigated in 3600 specimens. The milk shark diet was composed of teleosts, crustaceans, mollucs, nematodes, annelids, and unidentified invertebrates. R. acutus seemed to have a preference for teleosts (98.75% in terms of IRI). The trophic level of milk shark calculated in this study was 4.2.
