If a shark is coming toward you or attacks you,use anything you have in your possession to hit the shark's eye or gills.These are the areas most sensitive to pain. Make quick,sharp,repeated jabs in these areas. Sharks are predators and will usually only follow through on an attack if they have the advantage, so making the shark unsure of its advantage in any way possible will increase your chances of survival. Contrary to popular opinion,the shark's nose is not thearea to attack,unless you cannot reach the eyes or gills. Hitting the shark simply tells it that you are not defenseless.
