You Will Need
Try to stay calm. You're unlikely to run into the kind of shark that attacks humans unprovoked -- bull sharks, tiger sharks, and great whites. More likely, it will be a smaller species that will give you the once over and go away, as long as it doesn't feel threatened.
Begin swimming away, as smoothly and quietly as possible. Splashing around wildly and screaming will only call the shark's attention to you, and may even incite it to attack.
Get your back up
If the shark is approaching you and there's no time to swim away, try to back up against something to minimize the areas the shark can strike. If you're with a diving buddy, you'll both have a better chance to survive if you ascend while pressed together, back to back.
If the worst happens and the shark begins attacking, try to jab, punch, or kick them in its most sensitive areas -- the eyes, nose, and gills. Simply hitting them on the head will probably do more damage to your hand.
If you see someone else being attacked, don't hesitate to help them. Sharks are less likely to attack a rescuer and more likely to continue attacking the original victim.
Take heart: you'll probably never have to use any of this information because your chances of being attacked by a shark are one in 11.5 million.
