This is the world's largest synchronized breeding event.

这种同步繁殖景象是地球上最为宏大的。

On any one of these nights, trillions of eggs and sperms are released, flooding the entire 2000-kilometer length of the reef.

仅一个这样的晚上，就会有上万亿的卵子和精子排出，漂浮在绵延2000公里的珊瑚礁海岸线上。

By spawning at this precise moment, the corals have caught ally in the tide, allowing sperms and eggs of the same species to meet and fertilize.

这种精准的同步产卵机制让珊瑚虫抓住了短暂的潮汐间隙，完成同种内的受精。
