🧠 The Daily Fact #19

There’s a jellyfish known as Turritopsis dohrnii that is essentially immortal. Dubbed the "immortal jellyfish," it can revert its cells to an earlier stage of development after reaching maturity, effectively restarting its life cycle. This process, called transdifferentiation, allows it to avoid aging and potentially live forever—barring predation or disease. Scientists are studying this jellyfish to understand how its unique ability might offer insights into cellular regeneration and aging in humans. For now, it remains one of nature’s most fascinating biological cheats.
