[Diet of two selachians common to the Gulf of Gabes (Tunisia): Rhinobatos rhinobatos (Linnè, 1758) and Rhinobatos cemiculus (Geoffroy Sainte-Hilarie, 1817)].

Rhinobatos rhinobatos and Rh. cemiculus are two digging species with a malacophagic and, accessorly ichthyophagic diet. Rh. rhinobatos' main prey is Hermione hystrix. Rh. cemiculus' one is Citharus macrolepidotus. This study points out that it exists few seasonal changes about the diet of these Selacians.
