【双语新闻】自然美景不一定是个好事
Moonlight triggers the world’s biggest orgy, strange creatures emerge from the depths, and waves glow blue. Some phenomena in the ocean can only be witnessed after dark.
月光触发了世界上最大的狂欢，奇怪的生物从深处冒出来，波浪里发出蓝色的光芒。海洋中的一些现象只能在天黑以后才能看到。
Such as bioluminescence makes the sea shimmer
比如生物发光使海水闪烁。
You may have seen the pictures.Dinoflagellates emit blue light when they’re disturbed, like at this bay on Vaadhoo Island in the Maldives
你可能看过照片，当藻类被扰动时，它们会发出蓝光，就像马尔代夫的瓦德胡岛的海湾出现的那样。
It’s night-time in an impossibly exotic location. Waves are breaking on the beach. The water is sparkling with electric blue lights.
这是在一个不可能有异国情调的地方的夜晚。海浪在沙滩上掀起。水里闪烁着蓝光。
The internet loves an image of a magical-looking bioluminescent bay. You may also have seen travel bloggers bemoaning the real event as not quite living up the hype.
网络上可以出现像魔术般的视觉效应的生物发光海湾图片。你也可以看到有些旅游博客上叹息这是真实的事件而并非虚假炒作。
Even if the latter is true, bioluminescence (in this case usually caused by planktonic organisms called dinoflagellates) is a pretty amazing natural phenomenon.
即使后者是真实的，生物发光(在这种情况下通常是由浮游生物甲藻造成)仍是一个相当惊人的自然现象。
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.
在受到扰动时，甲藻会发出蓝光，这就是为什么它们可以在浪花上，在船只周围，或者当一只手或划桨穿过它们的时候闪闪发光。
These tiny creatures are the most common source of bioluminescence at the ocean’s surface.
这些微小的生物是海洋表面生物发光最常见的来源。
So-called bioluminescent bays such as in Puerto Rico and Jamaica are among the best-known places to witness the glow. However, the ephemeral phenomenon can be found throughout the ocean where there are dense gatherings of dinoflagellates.
在波多黎各和牙买加等地的所谓有着生物发光的海湾，都是见证这一发光现象的最著名的地方。然而，这种转瞬即逝的现象在任何有大量的蓝藻聚集海洋中都能找到。
Sometimes dinoflagellates’ population increases rapidly causing blooms, which by day are coloured a less attractive red-brown, sometimes known as red tides. And some, but not all, of these red tides are poisonous.
有时，鞭毛虫的数量会迅速增加，导致水华，白天就会变成不那么吸引人的红棕色，有时也被称为赤潮。有一部分赤潮是有毒的。
