Definition
The genus Sphyrna includes all species of hammerhead sharks, which are characterized by their unique hammer-shaped heads (cephalofoil). These sharks are found in warm and temperate waters worldwide. Think of 'genus Sphyrna' as the VIP section for hammerheads; it's where all the hammer-shaped-head coolness resides. The cephalofoil enhances sensory perception and maneuverability. These sharks are generally active predators.
