5. Myth: Wild dolphins are friendly and will save humans in trouble.

谬误5：野生海豚非常友好，总是拯救陷入困境的人类。

Dolphins don’t particularly care for humans; why would they? They are after all wild carnivores of the ocean. The myth that wild dolphins are friendly and will haste to your assistance when you’re in trouble is a result of their curious nature which is often mistaken for caring or friendliness. For example, dolphins swimming next to boats are doing so in order to ride the boats wake, allowing them to use less energy to swim; not because of their love for all things human. In fact many people have been bitten or injured while attempting to swim with wild dolphins (we’re not talking about the trained dolphins seen at marine parks). There is, however, one way in which dolphins are helping humans: recent research is helping scientists understand how dolphins survive shark attacks, and their tissue-regeneration and anti-bacterial properties are considered nothing short of a medical miracle.

海豚并不特别关心人类，它们凭什么要这样做呢？它们毕竟是海洋中的野生食肉动物。俗说野生海豚非常友好，当你遇到麻烦总是急忙赶来帮忙，实际上是因为它们好奇的天性，常常被误认为是出自关心或友好。例如，海豚在渔船旁边游是为了借力船的尾流，这样它们游起来更省力，不是因为它们喜爱一切人类的东西。事实上，许多人在试图与野生海豚同游(我们说的不是在海洋公园看到的训练有素的海豚)时被咬过或受伤。然而，海豚有一种方式帮助人类：最近的研究帮助科学家了解海豚在鲨鱼袭击中活下来，它们的组织再生和抗菌性能被认为简直就是一个医学奇迹。
