A shark attack is an attack on a human by a shark. Every year around 100 shark attacks are reported worldwide. Seventeen fatalities were recorded as having being caused by shark attacks in 2011, out of 118 recorded attacks. Despite their relative rarity, many people fear shark attacks after occasional serial attacks, such as the Jersey Shore shark attacks of 1916, and horror fiction and films such as the Jaws series. Almost all shark experts consider that the danger presented by sharks has been exaggerated. The creator of the Jaws phenomenon, Peter Benchley, attempted to dispel the myth of sharks being man-eating monsters in the years before his death.

A drum line is an aquatic device used to reduce the amount of shark attacks in popular beaches by capturing the shark on the drum line's hook. While most drum lines are used in addition to the shark net, it has been proven that the drum line is more effective at catching the three most dangerous shark species (Great white, Bull and Tiger). A shark net is a net that is left submerged underwater in order to capture potentially harmful sharks. The combination of drum lines and shark nets have been proven to be successful in reducing shark attacks in the areas protected by them. Since the shark nets and drum lines have been put into use, there has only been one death caused by a shark attack on a protected beach.

The drum line consists of a drum, with two lines attached to it, one line is attached to an anchor going to the sea floor, the other has a baited shark hook. In order to keep people from stealing the drum, it is filled with a rigid polyurethane foam, which both helps it float, and fills it to keep it from being stolen out of the water for storage. In order to attract sharks, the hooks are baited with red mullet and false jacopever. Since the objective of the drum line is to get sharks away from popular beaches, not to attract the sharks to the beaches, only about 500 grams of bait are added to each hook to reduce the attraction of sharks. The sharks can only sense these baits from a couple hundred meters away.

Fish Sharks


Chondrichthyes (/kɒnˈdrɪkθɨ.z/; from Greek χονδρ- chondr- 'cartilage', ἰχθύς ichthys 'fish') or cartilaginous fishes are jawed fish with paired fins, paired nares, scales, a heart with its chambers in series, and skeletons made of cartilage rather than bone. The class is divided into two subclasses: Elasmobranchii (sharks, rays and skates) and Holocephali (chimaeras, sometimes called ghost sharks, which are sometimes separated into their own class).
