Turritopsis nutricula


Turritopsis nutricula is an immortal jellyfish. This Benjamin-Button-of-the-Deep can age backwards and is silently invading the world’s oceans, National Geographic News reports.

After reaching sexual maturity, this jellyfish is able to reverse its aging process and become a polyp again. The ability to reverse the life cycle is probably unique in the animal kingdom, and allows the jellyfish to bypass death, rendering the Turritopsis nutricula biologically immortal. Lab tests showed that 100% of specimens reverted to the polyp stage.
