海洋生物在珊瑚礁中生存就有点像生活在“美黑床”上一样,当太阳光线透过水照射下来,又经过珊瑚反射出来,这样光线从上方和下方一齐照射到珊瑚虫、与珊瑚虫共生的光合藻类以及其他生活在珊瑚礁中的海洋生物上面。那么这些生物为什么没有被晒死呢?一项最新的研究表明:珊瑚礁起着防晒的作用,吸收了太阳光中的紫外线,从而减少了对礁内海洋生物造成的伤 Living in a coral reef, marine life is a bit like living on a “black bed.” When the sunlight shines through the water and is reflected by corals, the light shines on the coral from above and below, cohabiting with corals Photosynthetic algae and other marine life living in coral reefs. So why are not these animals sunburn? A recent study shows that coral reefs play a role in sun protection, absorbing UV rays from sunlight and reducing the damage to marine life on the reef
