[00:00:00]There is an animal alive right now that cannot die of old age.

[00:00:03]The Turritopsis Dohrnii jellyfish, when stressed or injured, reverses its own aging, shrinking back into a juvenile state and starting its entire life cycle over again.

[00:00:13]It's not a metaphor.

[00:00:14]Its cells literally revert to an earlier form, like hitting an undo button on existence.

[00:00:20]Scientists call it transdifferentiation, and no other complex animal can do it.

[00:00:25]This jellyfish isn't surviving death, it's just refusing to arrive there.

[00:00:29]While humans spend billions chasing longevity, this tiny transparent creature figured out biological immortality millions of years before we even existed. See you on the next interesting fact.
