‎Did you know that there are "immortal" jellyfish? The species Turritopsis dohrnii has the remarkable ability to revert its cells to an earlier state, essentially reversing its aging process. When injured or threatened, this jellyfish can transform back into a polyp, its earliest form, and begin its life cycle anew. This process can theoretically go on indefinitely, making the jellyfish biologically immortal, though in nature, they often fall prey to disease or predators before they can exploit this ability fully. It's one of the few known examples of a creature that can cheat death in such a direct way!
