Some jellyfish species may be 'biologically immortal'. "We studied their metabolic rates for the first time a couple of years ago and discovered that they have very slow metabolisms, unsurprising given they're large cold-blooded fish living in the freezing waters of the Arctic (metabolism slows with decreasing body temperature and increasing body mass)," Eric Ste-Marie, a marine ecologist and Greenland shark researcher at the University of Windsor in Canada, told Newsweek.
