白化之后的珊瑚，为什么还有可能被"救回来"？
Why can bleached coral still be "saved"?
白化是胁迫下的"罢工"而非立刻死亡，若高温短期结束，虫黄藻能重新入住；但反复白化会耗尽珊瑚体力，最终真正死亡。
Bleaching is a stress "strike," not instant death; if heat ends soon, zooxanthellae can return. Repeated bleaching exhausts corals until they truly die.

珊瑚礁只占海面约 1%，为什么却能养着约 1/4 的海洋物种？
Reefs cover only ~1% of sea surface, so why do ~1/4 of marine species live there?
三维的珊瑚结构像城市，提供无数洞穴、缝隙和食物链位；空间复杂又食物丰富，于是小小礁盘成了海洋里的"物种公寓"。
3-D coral structure is like a city with countless caves, crevices and feeding niches; complex space and rich food make a small reef a marine "species apartment".

珊瑚和虫黄藻，为什么是"共生"关系？
Why are corals and zooxanthellae in "symbiosis"?
虫黄藻住在珊瑚体内，靠光合作用给珊瑚供糖和氧；珊瑚则提供保护与二氧化碳，双方互相"喂饭"，离了对方都难活。
Zooxanthellae live inside corals, photosynthesizing sugar and oxygen for them; corals give shelter and CO₂—each feeds the other, and apart both struggle.

珊瑚白化，为什么是"热"出来的？
Why is coral bleaching caused by "heat"?
海水持续偏暖会让珊瑚把体内的虫黄藻排走，失去颜色与主要营养来源，露出白骨般的碳酸钙；温度一恢复正常，有的还能重新"上色"。
Prolonged warm water makes corals expel their zooxanthellae, losing color and main food, leaving white calcium-carbonate skeletons; if heat eases, some can regain color.
