Anatomy

Sharks have a muscular system arranged in a series of bands that extend the length of the body, allowing for quick and powerful movements. Sharks have fins that provide stability, maneuverability, and lift. Typically they will have two dorsal fins. The first being larger then the second, located on the sharks back. The pectoral fins are located on either side of the body. They are used for steering, and can move independently. Pelvic fins are located on the underside of the shark, and are smaller then the pectoral fins. The anal fin is located on the underside of the body near the tail. The caudal fin, or the tail is used for propulsion. It is divided into the upper and lower lobes. The shape varies depending on the species.  

Besides size, great hammerheads are distinguished by their heads hammer shape, referred to as a cephalofoil. Their eyes are set at each end of the hammer. They have a 360 degree range of vision, they can't see directly in front, but they can see above, and below them. Their nostrils are spread apart in the front of the head, rather then close together as with a typical shark. There is a prominent indentation at the midline. All sharks are capable of locating prey, using special sensory organ known as ampullae of Lorenzini. However the hammerheads cephlafoil is much stronger, having an increased number of electrical sensors . They have highly sensitive gel-filled pores, concentrated on the bottom of their head. They are capable of picking up extreamily weak emissions from prey, like the stingray, who hides under the sand.
