The cephalofoil of great hammerheads is between 23-27% of the body length and has a characteristic look that many people associate with hammerheads. It is likely that hammerhead sharks evolved the cephalofoil at least in part to provide more explosive and stable maneuvering. Hammerheads use their heads not only to detect prey but also as a weapon to capture it. The Sexually Dimorphic Cephalofoil of Bonnethead Sharks, Sphyrna tiburo STEPHEN M. KAJIURA1,*, JOHN P.
