Which organism is described as undergoing a constant cycle of maturity and immaturity, effectively living forever?

Explanation:
The main idea is life-cycle reversal: a creature that can go from adult back to a juvenile form and start over, potentially living indefinitely. Immortal jellyfish do this through a process called transdifferentiation, where mature tissues are transformed into new polyp tissue, effectively resetting development. Because it can repeatedly revert to the juvenile stage and then mature again, it can cycle between maturity and immaturity for as long as it avoids death from disease, predation, or environmental harm. The other terms aren’t established as species with this capability, so they don’t describe an organism that truly does this.
