The “immortal” jellyfish, Turritopsis dohrnii, has an extraordinary survival trick: when injured, starving, or aging, it doesn’t die—instead, it transforms its adult body back into its juvenile polyp stage through a process called transdifferentiation. This means its cells essentially reprogram themselves, turning into different types, like stem cells do. Once it reverts to the polyp stage, it can grow into an adult all over again. This cycle could theoretically repeat indefinitely, making it biologically immortal. While it can still be eaten or destroyed by disease, its ability to reset aging is unique in the animal kingdom and holds fascinating potential for regenerative medicine research.

This is incredible! What stops the jellyfish cells from accumulating mutations in their genomes?
I have a friend who does this. He's pretty chill.
