鯊魚會獵捕人類嗎？
Despite their scary reputation, sharks very rarely attack humans. They would much rather eat fish and marine mammals.
Of the more than 300 species of sharks, only about a dozen have ever been involved in attacks on people. Sharks evolved millions of years before humans existed, so humans are not part of their normal diet. Sharks will eat whatever is available, but most feed mainly on smaller fish and invertebrates. Some of the larger species hunt seals, sea lions and other marine mammals.
Sharks sometimes attack humans when they are confused or curious. If a shark sees a person splashing in the water, it may come closer to investigate, which can lead to an accidental bite.
In fact, sharks have much more to fear from us than we do from them. People hunt sharks for their meat, organs, skin and fins, which are used to make products such as shark fin soup, oils and leather. Sharks play an important role in ocean ecosystems, but overfishing is threatening some shark populations. Scientists are studying where sharks live, how they migrate and how their numbers are changing, to find the best ways to protect them.
鯊魚雖然名聲嚇人，卻很少攻擊人類。牠們比較喜歡吃魚和海洋哺乳動物。
在 300 多種鯊魚中，只有大約十幾種曾經攻擊過人。鯊魚在人類出現之前幾百萬年就已經演化出來了，所以人類並不在牠們平常的菜單上。鯊魚有什麼吃什麼，但大部分鯊魚主要吃小魚和無脊椎動物。一些體型較大的鯊魚會獵捕海豹、海獅和其他海洋哺乳動物。
鯊魚有時會在困惑或好奇的時候攻擊人類。如果鯊魚看到有人在水裡拍打水花，牠可能會游過來看個究竟，結果意外咬傷人。
其實，比起我們怕鯊魚，鯊魚更該怕我們。人類捕殺鯊魚，是為了牠們的肉、內臟、皮和鰭，用來做魚翅湯、油和皮革等產品。鯊魚在海洋生態系中扮演重要的角色，但過度捕撈正在威脅一些鯊魚族群。科學家正在研究鯊魚住在哪裡、怎麼遷徙、數量怎麼變化，好找出保護牠們的最好方法。
