Turritopsis Nutricula(infinite app) has to do with this mysterious natural phenomenon, which is beyond all co- gnition on human nature. The jellyfish reproduces itself asexually and its cells split continuously, from infancy to adulthood, and adulthood back to infancy. It is evidence of immortality found in nature. aaajiao transfers the jellyfish from the living into the digital form, as the examination and reflection on this phenomenon.

Turritopsis nutricula, the potentially immortal jellyfish, is a hydrozoan whose medusa, or jellyfish, form can revert to the polyp stage after becoming sexually mature. It is the only known case of a metazoan capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary stage.[2][3] It does this through the cell development process of transdifferentiation. Cell transdifferentiation is when the jellyfish "alters the differentiated state of the cell and transforms it into a new cell." In this process the medusa of the immortal jellyfish is transformed into the polyps of a new polyp colony. First, the umbrella reverts itself and then the tentacles and mesoglea get resorbed. The reverted medusa then attaches itself to the substrate by the end that had been at the opposite end of the umbrella and starts giving rise to new polyps to form the new colony. Theoretically, this process can go on infinitely, effectively rendering the jellyfish biologically immortal,[3][4] although in nature, most Turritopsis, like other medusae, are likely to succumb to predation or disease in the plankton stage, without reverting to the polyp form.[5] No single specimen has been observed for any extended period, so it is not currently possible to estimate the age of an individual, and so even if this species has the potential for immortality, there is no laboratory evidence of many generations surviving from any individual..(.wikipedia)
