Immortal Jelly Fish:

One of the Top 10 Long-Lasting AnimalsJellyfish

Folks are interested in the immortal jellyfish because it can change back to its juvenile stage after it has reached old age, essentially starting its life cycle over again. Transdifferentiation is the word for this effect.

  • Estimated Lifespan:

No one knows for sure how long an immortal jellyfish can live. Their normal life cycle stages allow them to repeat themselves, but in general, they have an estimated lifespan of two to three years.

  • Reasons for Longevity:
  1. Life Cycle Reversal: In response to stress, harm, or the effects of aging, the immortal jellyfish has the remarkable ability to regenerate its cells into younger ones, effectively reversing the effects of time.
  2. The jellyfish is able to regenerate and begin its life cycle again by undergoing cellular transformation, a process known as transdifferentiation. This allows it to change its specialized cells, such as muscle cells, into other cell types.
