For all the terror they generate, fatal shark attacks are pretty rare — there are usually only a handful in a year.
That said, no reason to tempt fate by doing things that make you more likely to be shark bait. For instance, try not to swim at night or at twilight, a time when sharks tend to be more active. Try to stay in groups because sharks are much more likely to attack someone swimming alone. Don't wear shiny jewelry because anything that reflects light can, to a shark, look like fish scales. And obviously, don't stray too far from shore; it will make it that much harder for you to get to safety or get help if a shark bites you.
LOSE THE JEWELRY
Don't wear shiny jewelry because anything that reflects light can, to a shark, look like fish scales. And obviously, don't stray too far from shore; it will make it that much harder for you to get to safety or get help if a shark bites you.
The problem is that most shark bite victims don't see the big fish coming. Usually, the attack comes by surprise. It may seem small consolation, but sharks don't like to eat humans. More often than not, they mistake them for seals, which they really do like to eat.
HIT HIM IN THE EYE
But that doesn't mean much once a shark bites or if he holds on and pulls his victim underwater. At that point you need to fight back. You gain nothing by trying to play dead. If you have a spear gun or camera, hit the shark in the eye. Or if you get the chance, grab his gills on the side of his body; they are particularly sensitive.
With luck, the shark will spit you out. Once free you need to get out of the water as soon as possible. But even before you're out of the water, do what you can to staunch any bleeding. Losing a tremendous amount of blood is the greatest threat to your life.
And remember, the majority of shark bites are definitely survivable.

惊魂全记录-鲨口脱险
在各种灾难中，被鲨鱼攻击是很罕见的，一年里面发生的次数很少，也就是说，不要冒险，故意让自己成为鲨鱼攻击的目标。例如，不要在夜晚或黎明时游泳，这个时候的鲨鱼最活跃，而且最好是集体活动，因为鲨鱼倾向攻击落单的泳客，也不要配戴会闪闪发亮的饰品，那些会反光的东西对鲨鱼来说就像鱼鳞一样，另外，当然不要游离岸边太远，一旦遭遇鲨鱼时，您可能无路可逃。
脱掉饰品
不要配戴会闪闪发亮的饰品，那些会反光的东西对鲨鱼来说就像鱼鳞一样吸引他。还有，当然不要游离岸边太远，一旦遭遇鲨鱼时，您可能无路可逃。
重点是，被攻击的人往往都没有察觉到鲨鱼靠近，而是突然被袭击。鲨鱼其实并不喜欢吃人，他们常只是误把人类当成最爱的海豹。
攻击眼睛
一旦被鲨鱼攻击，或被拖入海底，不管你是人或是海豹都不重要了，在这个这时候，该做的就是反击，装死是没有用的。如果有鱼叉或照相机，直接攻击鲨鱼的眼睛，如果逮到机会，攻击他的鳃，那是最脆弱的地方。
幸运的话，他会把你吐出来，脱身后，尽快离开水面，但是在离开之前，尽可能地帮自己止血，失血过多将危害您的生命。
记住，大部份被鲨鱼攻击的人最后都生还了。
