I'm beginning to think that when you go to the shore, you could see the moon shining over the sea. Well, as the moon's light is weaker than the sun, deep areas may never be reach but I don't think there could be many reefs in very deep parts.
There are occasions when the sea becomes completely dark especially when the clouds are covering the moon or during storms. Well, the corals may survive without the moonlight but don't just go on switching off the moonlight almost every night.
Now, I can't apply any more logics.
