Scientists have discovered a jellyfish which can live forever. Turritopsis dohrnii is now officially known as the only immortal creature. ... It turns out that once the adult form of the 4.5 mm-wide species Turritopsis dohrnii have reproduced, they don't die but transform themselves back into their juvenile polyp state.

There are two distinct stages of a jellyfish’s life cycle: the polypoid stage and the medusa stage.
It is no different to the turritopsis dohrnii, except that it can revert to its polyp stage at any time.
In order to do this reversion, the immortal jellyfish will use tissue from the circulatory canal system as well as the bell surface and the process used is called transdifferentiation.
But in order to undergo this transformation, the jellyfish develops somehow some missing cell types like sensory cells.There is insufficient data regarding this
The rejuvenated jellyfish will reach its sexual maturity in less than 30 days if the water temperature is 20 degrees Celius or in 18-22 days if the water temperature is 22 degrees. After it reached maturity, it doesn’t automatically revert to its former statute.
