"Turritopsis dohrnii has the ability to turn back into a baby jellyfish and grow up all over again"

"Immortality is generally considered the realm of the gods or science fiction, a fantasy that’s actively pursued by tech entrepreneurs in macabre experiments that include injecting “young blood”, cryopreservation, or resurrection in an AI afterlife.

But one ethereal, thimble-shaped jellyfish has already cracked the code.

As associate professor Maria Pia Miglietta, a marine biologist at A&M University in Texas, explains, Turritopsis dohrnii has an incredible ability to cheat death.

“Turritopsis is unique, because when faced with unfavourable conditions – and I mean high temperature, physical cutting, starvation, chemicals in the water, you name it – when you try to kill the jellyfish, it doesn’t die.”"
