Dinoflagellates are one of the biggest single-celled organisms known to man.

甲类已知的最大的单细胞生物之一。

Imagine a shrimp comes along and starts feeding on dinoflagellates by filtering them out of the water.

想象一下，一只虾游过来，开始从水中过滤甲并以此为食。

According to the Monterey Bay Aquarium, a mass bloom of dinoflagellates caused this bright light.

据蒙特利湾水族馆介绍，大量的甲繁殖导致了这种明亮的光芒。

Bioluminescent tides like this are rare, but dinoflagellates are found in huge numbers all over the world.

像这的生物发光潮汐很少见，但在世界各地都发现了大量甲。

90% Of all dinoflagellates are marine plankton, and when conditions are right in the sea, they bloom in enormous numbers.

90% 的甲都海洋浮游生物，当海洋条件适宜时，它们就会大量繁殖。

Just as a flashing burglar alarm alerts police to a thief, the dinoflagellates expose their attacker to its enemies.

就像闪烁的防盗警报器提醒警察注意小偷一，甲者暴露给敌。

In this case, a cuttlefish catches the shrimp, and the dinoflagellates don't need to be afraid anymore.

这一来， 乌贼就抓到了虾，甲就不用再害怕了。

These, Dr Mincer and Dr Amaral-Zettler found in the form of dinoflagellates, some of which like to snack on smaller creatures to supplement their photosynthesis.

明瑟及阿玛拉尔-特勒两位博士以甲的形式发现了食草动物的存在, 一些甲喜欢吃小型生物作为他们光合作用的补充。

Left alone, dinoflagellates won't produce much light, but if something like an ocean wave, a current, or a human disturbs them, they will flash brightly.

甲独自生存时不会发出太多的光，但如果受到海浪、洋流或类等物质的干扰，它们就会发出明亮的光芒。

If you're a single-celled organism like a dinoflagellate, you're at the bottom of the food chain, so avoiding getting eaten involves hard work every day.

如果你像甲这的单细胞生物，那么你就处于食物链的底端，因此为了避免被吃掉， 你每天都需要付出艰苦的努力。
