As such, the immortal jellyfish offers an important lesson, says Maria Pascual-Torner of Spain’s Institute of Marine Sciences, who conducted the 2022 study with Quesada. “Although it has the ability to rejuvenate and, theoretically, not die from ageing, it is at the same time an extremely vulnerable organism,” she says. “The immortal jellyfish also reminds us that life and death are inseparable parts of the same reality.” In other words, even nature’s most immortal organism has to face death.
