The everlasting jellyfish Turritopsis dohrnii descends to the ocean floor and begins to decompose when it dies. Turritopsis dohrnii, the so-called “immortal jellyfish,” may miraculously reassemble its cells and return to an earlier embryonic stage if it is wounded.
Because the jellyfish Turritopsis dohrnii does not die of natural causes, determining an average lifespan is impossible. By repeatedly reverting. If the jellyfish suffers “physical harm or even famine,” they revert to a polyp and restart their development process.
According to BBC Earth, Turritopsis dohrnii is able to do this because of a rare mechanism known as cellular trans differentiation.
Even when a jellyfish dies, it can miraculously resurrect. The corpse of the medusa sinks to the ocean floor and begins to decompose.
However, its cells begin to clump together, not into a new medusa, but into polyps, and new jellyfish arise from these polyps, according to BBC Earth. The jellyfish has returned to an earlier stage of life to start over. Except for jellyfish, all animals and humans perish.
