【英语时差8,16】与鲨鱼游泳

（单词翻译）

 In the immortal¹ words of Michael Corleone in The Godfather, Part II,”My father always taught me: keep your friends close, and your enemies closer.” Perhaps no creature has taken this advice more literally² then the remora, also known as the sucker fish. As the official ocean survival manual clearly states: “Upon spotting a shark, flee, unless you also happen to be a shark.” Or a remora. When a shark approaches, not only does the remora not flee–it swims right up to the shark, finds a nice comfortable spot, and attaches itself with a suction cup located on the top of its head. Why, you may be wondering, would any fish want to be so close to a predator³? If remoras could talk, they would calmly explain something called commensalism–a relationship where one species benefits from proximity⁴ to the other without harming or helping⁵ the other species. In this case, remoras benefit from riding on sharks without doing the sharks any harm.
