Coastal Tide Pool

This is an unedited picture of a coastal tide pool. I was amazed when I saw this picture for the first time because the shape of the small pool looks very unnatural and it also looks like something you would see on another planet. I think this particular hole was created in a very long period of time because in nature something this precise cannot be created in an instant. I wonder if we can fill up the pool with fluorescent fluid and see what it looks like at night.
