[00:00:00]What if you could hit a reset button on your life every time you got old or sick? Most creatures are born, age, and die, but there is one organism in the deep sea that has figured out how to cheat death forever. Meet [music] the immortal jellyfish, Turritopsis Dohrnii.

[00:00:18]This tiny, translucent creature has a biological superpower called [music] transdifferentiation.

[00:00:24]When it faces a crisis like starvation or old age, it doesn't simply die.

[00:00:29][music] Instead, it shrinks its body, retracts its tentacles, and sinks to the seafloor. It then transforms its mature [music] cells back into their earliest possible state, literally turning back into a baby polyp to start its life cycle all over again. It's like a butterfly turning [music] back into a caterpillar, then hatching again as a brand new butterfly. It is [music] the only animal known to be biologically immortal. Hit follow if you want to dive deeper [music] into the secrets of the abyss.
