Turritopsis dohrnii, the immortal jellyfish, achieves biological immortality through transdifferentiation, a cellular process where cells completely transform into different cell types, allowing the jellyfish to revert from its adult medusa stage back to its juvenile polyp stage and restart its entire life cycle repeatedly when stressed, injured, or aging.

This jellyfish just resets to baby mode #ShortsAdded:
Turritopsis Dohrnii, the immortal jellyfish, literally cheats death by becoming a baby again. When it gets old, injured, or stressed, it doesn't die. It reverts all the way back to its juvenile polyp stage, [music] and then restarts its entire life cycle from scratch. This is not metaphor. This is not science fiction. The cells physically transform, a process called [music] transdifferentiation, where one type of cell becomes a completely different type of cell.
Scientists are genuinely studying this to understand human aging. And meanwhile, the jellyfish is just out [music] there, cycling through life like it's got infinite save points. So, tell me, terrifying, [music] brilliant, or both?
