珊瑚是一种奇妙的海洋生物。人们对它的认识是经历了一个相当长的历史过程。最早的记载见于我国的汉代,说它“贯中而生,高二三尺,有枝无叶”。显然,认为它是一种曾未见过的奇异的植物。在西方直到16世纪,西班牙的航海家在经过红海时,才首次留下对它所作的描述。17世纪,法国科学家庇拉尔曾在马尔代夫作过考察。这次他绘制了马尔代夫环礁全图。1774年,又一位法国人在对北非沿岸考察时,这才意外地发现了原来像花一样的植物,竟是一种贪婪的肉食者。不过,他的发现非但没引起重视,反而招惹来了讥讽误认为他是在胡言乱语。直到19世纪40年代,珊瑚才还其动物的本来面目。如今,没有谁会再把它当成植物了。 Coral is a wonderful marine life. People’s understanding of it has undergone a fairly long historical process. The earliest records found in our Han Dynasty, said it “born in the middle, two or three feet high, there is no leaves ”. Apparently, it is a strange plant that has never been seen before. In the West until the 16th century, Spanish navigators left the description of it for the first time as they crossed the Red Sea. In the 17th century, French scientist Peilah visited the Maldives. This time he mapped out the Maldives Atoll. In 1774, when another Frenchman inspected the coast of North Africa, he unexpectedly discovered that the original flower-like plant was actually a greedy meat-eater. However, his discovery not only failed to pay attention, but provoked misunderstanding that he was nonsense. It was not until the 1840s that coral found its natural beauty. Now, no one will treat it as a plant anymore.
