It is the only known case of an animal capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as
a solitary individual.
. All the polyps and jellyfish arising from a single planula are genetically identical clones. If a T. dohrnii jellyfish is exposed to environmental
stress or physical assault, or is sick or old, it can revert to the polyp stage, forming a new polyp colony. It does this through the cell
development process of transdifferentiation, which alters the differentiated state of the cells and transforms them into new types of cells.
Theoretically, this process can go on indefinitely, effectively rendering the jellyfish biologically immortal, although, in nature, most
Turritopsis are likely to succumb to predation or disease in the medusa stage, without reverting to the polyp form
