F-2. Sharks are potentially the most dangerous fish that attack people. The obvious danger of sharks is that they are capable of seriously maiming or killing you with their bite. Of the many shark species, only a relative few are dangerous. Most cases of shark attacks on humans are by the white, tiger, hammerhead, and blue sharks. There are also records of attacks by ground, gray nurse, and mako sharks. Figure F-1, shows various sharks and their sizes.

F-3. Avoid sharks if at all possible. Follow the procedures discussed in Chapter 16 to defend yourself against a shark attack.
F-4. Sharks vary in size, but there is no relationship between the size of the shark and likelihood of attack. Even the smaller sharks can be dangerous, especially when they are traveling in schools.
F-5. If bitten by a shark, the most important measure for you to take is to stop the bleeding quickly. Blood in the water will attract more sharks. Get yourself or the victim into a raft or to shore as soon as possible. If in the water, form a circle around the victim (if not alone), and stop the bleeding with a tourniquet.
