What Animal?

It is capable of cycling from a mature adult stage to an immature polyp (the first stage) stage and back again, therefore there may be no natural limit to its life span. Scientists say the hydrozoan jellyfish is the only known animal that can repeatedly turn back the hands of time and revert to its polyp state.

The key lies in a process called transdifferentiation, which is where one type of cell is transformed into another type of cell. Some animals can undergo limited transdifferentiation and regenerate their organs, but the turritopsi nutricula, on the other hand, can regenerate its entire body over and over again.

Because they are able to bypass death, the number of individuals is spiking. They're now found in oceans around the globe rather than just in their native Caribbean waters. It's a world wide silent invasion of jellyfish! Muahaha, I would rule the world!
