According to Boing Boing, there is a breed of jellyfish that has the ability to revert to an earlier stage of its life cycle and start over again. Since I have not yet completed by thesis on the life cycle of obscure jellyfish, I know absolutely nothing about this. But, it sounded fascinating. And a little terrifying. Think about what this would mean in human terms. To live forever, you’d have to revert to infancy and go through puberty all over again. Now that I think about it, maybe this is the jellyfish version of hell.
