“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.” “Theoretically it never has to die from getting old, it just keeps hitting the reset button.” Most normal jellyfish start off life as larvae. “When this jellyfish gets old or gets hurt, instead of just dying like most animals, it transforms itself back into a baby jellyfish and grows up all over again. With their delicate bodies and veil of tentacles, Lisa-ann Gershwin, a biologist specializing in jellyfish, describes Turritopsis as “exquisite” and “the most beautiful little creature.”
