The jellyfish that defies time

Just when we think we've seen it all, something comes along to surprise us. Such is the case of a marine creature that changes the rules of the game about aging and dying, because this animal, when it grows old and reaches the point of dying… is reborn!

The jellyfish that defies time

TL;DR

  • The Turritopsis dohrnii jellyfish can rejuvenate, reversing its life cycle when old, injured, or stressed.
  • This process, called cell transdifferentiation, allows specialized cells to revert to a stem-cell-like state.
  • While biologically immortal, the jellyfish can still die from predation, disease, or environmental damage.
  • Scientists are studying its genome to understand tissue regeneration and cellular aging for potential medical applications.
  • Other creatures, like some comb jellies, also exhibit similar developmental regression abilities.
