Unnatural selection

I've walked these beaches thousands of times, and seen most of the features on my wanderings, but the beauty of beaches are they change after every tide. I've seldom seen a rock pool so perfectly round, so it has to be Unnatural selection by Muse, even though it is perfectly natural. I'm just so pleased the rock was offset and not in the middle.
