Most jellyfish follow a one-way life cycle: larva, polyp, and then mature medusa.
However, Turritopsis dohrnii defies this natural order.
When faced with environmental stress or injury, it can transform its mature medusa body back into a polyp stage, essentially resetting its life.
According to Nature Journal, this extraordinary cycle is unique among known animals and underpins the jellyfish’s reputation for immortality.

The secret behind Turritopsis dohrnii‘s immortality lies in a remarkable process called cellular transdifferentiation.
This allows its adult cells to transform directly into different cell types, reverting to a juvenile state.
While some animals, like salamanders, can regenerate lost limbs, this jellyfish’s ability is far more extensive, involving a complete reset of its body.
As explained by Science.org, this unique cellular feat distinguishes the species from all other known animals and has become a focal point in regenerative biology research.

Environmental stressors—such as injury, sudden temperature changes, or starvation—often trigger Turritopsis dohrnii‘s remarkable transformation.
This ability appears to be an evolved survival mechanism, allowing the jellyfish to escape harsh conditions by reverting to a more resilient juvenile stage.
As National Geographic explains, this adaptive response is central to its reputation as the “immortal” jellyfish.

11. Implications for Human Aging Research
