How do jellyfish regenerate?
When the medusa the immortal jellyfish (Turritopsis dohrnii) dies, it sinks to the ocean floor and begins to decay. Amazingly, its cells then reaggregate, not into a new medusa, but into polyps, and from these polyps emerge new jellyfish. The jellyfish has skipped to an earlier life stage to begin again.
How does the immortal jellyfish regenerate?
In response to physical damage or even starvation, they take a leap back in their development process, transforming back into a polyp. In a process that looks remarkably like immortality, the born-again polyp colony eventually buds and releases medusae that are genetically identical to the injured adult.
How long does it take for an immortal jellyfish to regenerate?
But through his endeavours, Kubota has reported that over a two-year period, captive colonies of the jellyfish naturally rejuvenated themselves up to 10 times, sometimes at intervals of just one month.

What is the evolutionary significance of jellyfish?
Jellyfish are primitive animals which evolved in the oceans around 600 million years ago. Part of the reason for their evolutionary success is that some species are able to grow back tissue that has been lost—a trait that is rare in the animal kingdom.
