To most of us sharks are the most dangerous fish in the sea and they attack humans. However, according to Dr. Clark, who has studied the behavior of sharks for 12 years, humans are not normally on the shark's menu. What do sharks feed on? Mainly fish and other small sea animals. Dr. Clark also found that sharks don't eat as much food as people think. For instance, a nine-foot shark only needs two pounds of food a day to keep healthy. But she says, sometimes sharks starve and at other times they fill themselves with what they have killed.
對(duì)我們大多數(shù)人來(lái)說(shuō)，鯊魚是海里最危險(xiǎn)的魚類，而且它們攻擊人類。但是，研究了12年鯊魚行為的克拉克博士說(shuō)，鯊魚一般是不吃人的。那么鯊魚吃什么呢？主要是魚和其他小型海洋動(dòng)物?？死瞬┦窟€發(fā)現(xiàn)，鯊魚其實(shí)并沒(méi)有人類想像中吃的那么多。比如，一條九英尺的鯊魚一天只需要兩磅食物九可以保持健康。不過(guò)她還說(shuō)，鯊魚有時(shí)候會(huì)餓肚子，還有時(shí)候會(huì)殺掉什么就吃什么。
