LARGE sharks, such as the Great White and Tiger, generally prey on big marine mammals. So seals and dolphins as well as large fish and turtles need to keep an eye open at all times. But most shark attacks on humans are thought to be the result of mistaken identity—hapless bathers and seals apparently look much the same to these giant predators of the deep. But if you don’t want to fall prey to a shark (and the chances are fairly remote anyway) some places are safer than others according to data stretching back over 400 years from the University of Florida’s International Shark Attack File. Sharks don’t much like colder northern and southern waters but global warming may yet extend the range of these inadvertent man-eaters.
体型较大的鲨鱼,比如大白鲨和虎鲨,一般以大个头的海洋哺乳动物为食。所以海豹、海豚、海龟和其它大鱼都要时刻提防它们。但是,鲨鱼对人的攻击事件一般被 认为是由于鲨鱼对捕食目标的错误识别引起的——对于栖息在深海的巨型捕食者鲨鱼来说,倒霉的游泳者和海豹看起来是一样的。不过,佛罗里达大学国际鲨鱼攻击 档案(International Shark Attack File)400年来的数据显示,你若不想成为鲨鱼的猎物(其实机会相当渺茫),有些地方确实比其它地方安全些。鲨鱼不太喜欢南北半球的寒冷水域,但全球变暖或许扩大了这些无意的食人者的活动范围。
