During the lowest tides,the water runs off and whole sections of living coral are normally beyond the water,are exposed.
最低潮時(shí)，海水流干，活珊瑚露出全貌。正常情況被淹沒(méi)在水底的部分得以展現(xiàn)。
The level of water on the reef top decreases dramatically,getting ever shallower,and going from a stable environment,to ever changing hostile one.
珊瑚礁頂端的水位下降得很顯著，變得非常淺，從一種穩(wěn)定的狀態(tài)變成一個(gè)不停改變的危險(xiǎn)狀態(tài)。
It's almost as though some mighty force has lifted the reef right out of the water,these are extreme conditions.
就好像一種強(qiáng)大的力量舉起了珊瑚礁把它托出水面，這些都是非常極端的條件。
As the exposed corals start to heat up,
顯露出水面的珊瑚礁逐漸升溫，
the tiny polyps retract inside their stony skelectons for protection,
珊瑚蟲(chóng)退回到珊瑚骨架內(nèi)以保護(hù)自己。
then they secrete mucouscan,it acts as sunscreen, and there is no skimping on quantity,an area no larger than the size of a coffee table can produce five meters of the stuff.
接著它們開(kāi)始分泌有遮光作用的粘液，在分泌量上它們毫不吝惜。一張咖啡桌般大小面積的珊瑚蟲(chóng)就可以分泌出5升液體。
As the tides retreat to the edge of the reef,it cuts off pools of water,for most animals like the sea cucumboers and starfish,the best way to stay alive is by taking refuge in these rock pools.
在潮水完全退到礁石區(qū)以外后，留下的只有被礁石分割開(kāi)來(lái)的潮汐地。對(duì)于大多數(shù)動(dòng)物來(lái)說(shuō)，比如海參，海星，最佳的生存方法就是暫時(shí)避居在這些潮汐池中。
