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.
Who discovered immortal jellyfish? The species T. dohrnii was first described by scientists in 1883. It was 100 years later, in the 1980s, that their immortality was accidentally discovered. Students Christian Sommer and Giorgio Bavestrello collected Turritopsis polyps, which they kept and monitored until medusae were released.It was thought that these jellyfish would have to mature before ...

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. In other words, it can age in reverse and morph from an adult back into a baby. The jellyfish has the ability to become a younger version of itself - a spectacular survival mechanism that plays out when it gets old or sick or faces danger.
