The diet of the common cuttlefish Sepia officinalis was studied from samples collected in the coastal waters of Côte d’Ivoire, for 12 months. According to the qualitative analysis of the stomach contents of all these animals, fish and crustaceans represented respectively, 50.23% and 38.65% of the examined stomachs are the most regularly consumed prey. The monthly evolution of the vacuity coefficient shows that this index varies according to the sexual cycle. Juveniles feed primarily on crustaceans. The stomachs bowl of the adults contains fish but also crustaceans and cephalopods whose frequencies are relatively significant, which would let think that Sepia officinalis changes trophic behavior in connection with the evolution of its physiological state and that at the adult state, the animal acquires performances which enable him to apprehend the preys with fast movements in fact the fish.
