There is a Jellyfish whose biology allows it to go from a fully mature Medusa, to its polyp stage and back again indefinitely. The Turritopsis nutricula is a small jellyfish with an ability so far unique in the animal kingdom. It is the only known jellyfish to have developed the ability to return to a polyp state.

The process is called transdifferentiation.
