Natural Slumber

They are not islands at all, but jellyfish! Each of these floating circles is in fact a giant invertebrate organism. And they aren't dead, either: the seemingly fossilized state is just a natural part of their life cycle. Over the course of thousands of years, these stony islands release sediment until they finally dissolve completely. The sediment contains microscopic polyps that eventually germinate in the water until they enter the next stage of their life cycle.
