Well believe it because swimming around in the ocean right now is the ‘immortal jellyfish.’ Turritopsis dohrnii is a small jellyfish that can theoretically live forever through a process called transdifferentiation. And no this is not wizardry or some sci-fi fantasy. It’s a process that actually renews the jellies life, kind of like living forever young. You see, jellyfish start their lives as tiny larvae called planula floating around the ocean. Eventually that those planula grow up and settle down as little polyps that are attached to the sea-floor. Those polyps continue to grow tentacles and eventually break off as free roaming, swimming jellyfish. If turritopsis dohrnii is ever hurt, sick or growing too old, it is able to revert back to it's polyp stage and grow again as the same, but brand spanking new jellyfish, it’s like a benjamin button that never dies. Theoretically, this process can go on indefinitely, effectively making this jellyfish biologically immortal. So as long as they don’t get swallowed up whole by some hungry fish, they’ll be ringing in the year 3015.
