Turritopsis dohrnii, also known as the immortal jellyfish, is a species of small, biologically immortal jellyfish [2][3] found worldwide in temperate to tropic waters. It is one of the few known cases of animals capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual.
It has been dubbed the immortal jellyfish. When the medusa of this species is physically damaged or experiences stresses such as starvation, instead of dying it shrinks in on itself, reabsorbing its tentacles and losing the ability to swim. It then settles on the seafloor as a blob-like cyst.
If the start of jellyfish life wasn’t extraordinary enough, its death is where things get really exciting. 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.
How does the immortal jellyfish (Turritopsis dohrnii) live for so long? A leading scientist the stranger cellular science behind the creature's lifespan.
Jul 23, 2023 · When an immortal jellyfish (Turritopsis dohrnii) grows old or damaged, the species can evade death by reverting to a baby polyp stage. It does so by reabsorbing its tentacles and coming to rest as a blob of undifferentiated cells somewhere on the seafloor.
May 4, 2015 · 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. In fact, since this phenomenon was first observed in the 1990s, the species has come to be called “the immortal jellyfish.”
5 days ago · The immortal jellyfish is a species of tiny, translucent, jellyfish-like invertebrate animals of the phylum Cnidaria, which is renowned for its ability to evade death by cycling repeatedly between its polyp and medusa forms.

In the warm seas of the Mediterranean lives a jellyfish with an extraordinarily rare ability – it can rewind its life cycle. The so-called ‘immortal’ jellyfish, or Turritopsis dohrnii, can somehow reprogramme the identity of its own cells, returning it to an earlier stage of life.
