Turritopsis dohrnii. Immortal jellyfish

By: Turritopsis nutricula, the immortal jellyfish, is a hydrozoan whose medusa, or jellyfish, form can revert to the polyp stage after becoming.

Turritopsis dohrnii is a breed of jellyfish that is IMMORTAL. They win. There may or may not be a Turritopsis dohrnii out there that predates human civilization. To put it simply, the Turritopsis dohrnii recycles old cells through a process called transdifferentiation, in which one cell is turned into another type of cell.

Turritopsis nutricula - is a species of jellyfish, which not only has been endowed by nature biological immortality, but also the ability to radical rejuvenation.

Immortal Jellyfish: The Only Known Species Known to Live Forever -  Turritopsis dohrnii, is able to transform its cells from mature state back to immaturity, in other words – back to youth. The medusa leads a regular cycle of life, but after maturing and mating, it reverts back to its initial state – a polyp colony. The process is referred to as “transdifferentiation”, and it basically makes the jellyfish unable to die.

When a fully mature immortal jelly (Turritopsis dohrnii) undergoes stress of old age or environmental changes, it can pull a Benjamin Button and revert to an earlier developmental polyp stage! This is the only known animal that can un-age!
