Carnivorous, feeding largely on marine invertebrates, crabs, jellyfish, sponges, and occasionally fish. Young are largely pelagic, while adults stay closer to shore. Undergoes extensive migrations from and to nesting beaches, feeding grounds and seasonally to escape low temperatures. Nests sometimes on fairly disturbed beaches. A nest probably belonging to this species was found on a busy public beach in Alexandria in the 1970s (Baha El Din unpub. obs.). Many nests and nesting attempts detected by Clarke et al. (2000) were in fairly disturbed stretches of beach. Nesting in the eastern Mediterranean takes place between June and September (Clarke et al. 2000). Sexual maturity reached between 10 and 15 years (Schleich et al. 1996).
