The Immortal Jellyfish’s Age-Reversing Secret

The immortal jellyfish can literally reverse its aging process and become young again.

When this tiny creature faces stress or injury, it doesn't die. Instead,

its cells transform completely, turning back into a baby polyp stage. It's like a butterfly

becoming a caterpillar again. Scientists discovered this biological time travel in the

1990s, and technically, these jellyfish could live forever if nothing eats

them. They've spread across every ocean on Earth, multiplying endlessly. While we search

for anti-aging secrets, this jellyfish has already cracked the code to biological immortality,

making it the only known animal that can cheat death indefinitely.
