　　Even if the latter is true, bioluminescence (in this case usually caused by planktonic organisms called dinoflagellates) is a pretty amazing natural phenomenon.

　　即使后者是真的，生物熒光(在這種情況下通常是一種叫做“鞭毛”的浮游生物造成)也是一種非常神奇的自然現(xiàn)象。

　　Dinoflagellates emit blue light when disturbed, which is why they can be seen sparkling over wave crests, around boats or when a hand or paddle runs through them. These tiny creatures are the most common source of bioluminescence at the ocean’s surface.

　　當(dāng)受到干擾時，鞭毛蟲會發(fā)出藍色的光，這就是為什么它們會出現(xiàn)在海浪的波峰，在船只周圍，或者當(dāng)一只手或槳穿過它們的時候。這些微小的生物是海洋表面生物發(fā)光最常見的來源。

　　So-called bioluminescent bays such as in Puerto Rico and Jamaica are among the best-known places to witness the glow.

　　在波多黎各和牙買加等號稱生物發(fā)光的海灣是見證這一勝景的的最有名的地方。
