It looks like a certain kind of jellyfish has figured out the secrets of immortality…
In The World’s Only Immortal Animal, you will read about how a specie of jellyfish (turritopsis nutricula) reverses its aging process via transdifferentiation.
In other words, it transforms its cells from mature, back to the first stage of its life.
Yes, the jellyfish fountain of youth, if you will.
In short (or in long), they never die of old age.
What do you think will happen when they finally fill up the oceans? 😉
