Like other types of jellyfish, T. dohrnii goes through a two-part life cycle, living on the sea floor during an asexual phase, where its main role is to stay alive during periods of food scarcity. When conditions are right, jellyfish reproduce sexually. Although many types of jellyfish have some ability to reverse aging and revert to a larval stage, most lose this ability once they reach sexual maturity, the authors wrote. Not so for T. dohrnii. “We know that this species can do a little bit of evolutionary cheating for maybe 15-20 years,” said Monty Graham, a jellyfish expert and director of the Florida Institute of Oceanography who was not involved in the research. This ploy has given the species its nickname as the “immortal jellyfish,” a term that Graham admits is a bit of an exaggeration. The study aimed to understand what made this jellyfish different by comparing the genetic sequence of T. dohrnii to that of Turritopsis rubra, a close genetic cousin that lacks the ability to regenerate after sexual reproduction. What they found is that T. dohrnii has variations in its genome that may make it better at copying and repairing DNA. They also seem to be better at maintaining the ends of chromosomes called telomeres. In humans and other species, telomere length has been shown to decrease with age. Graham said the research has no immediate commercial value. “We can’t see that as we’re going to harvest these jellyfish and turn them into a skin cream,” he said. It’s more about understanding the processes and protein functionality that helps these jellyfish cheat death. “It’s one of those papers that I think will open a door to a new line of study that’s worth pursuing.”
