Turritopsis Nutricula, a species of jellyfish native to the Caribbean, has now spread to all corners of the ocean. Why? Because they don’t die:
Turritopsis Nutricula is technically known as a hydrozoan and is the only known animal that is capable of reverting completely to its younger self.
It does this through the cell development process of transdifferentiation.
Scientists believe the cycle can repeat indefinitely, rendering it potentially immortal.
This according to a Telegraph article about the interminable little critters.
Amazingly these jellies can reach sexual maturity, revert to a polyp state, then grow to sexual maturity again ad infinitum. But don’t flee the oceans just yet. The little fellas are only five millimeters long and are harmless….for now.
