Forgive me if this question is off topic, but I’ve seen similar questions so I think it should be on topic.
I’m at the beach currently, and I was looking in tide pools for interesting things. I found some coral in a one.
I don’t know exactly, but I think there are around 6 or so polyps in the tide pool.
It is very possible that I have misidentified these organisms as coral, when they are something else. If I have, let me know.
It is my understanding that coral survives with the help of algae, which produce food for them. However this tide pool barely gets sun, and is the only one I have found with coral.
Here is a (bad) drawing of the location.
As you can see, the amount of time that sun reaches this location is very short, so wouldn’t the coral be unable to thrive with little sun?
