Jun 19, 2020 · There is a debate among the scientific community whether these red ocean dwellers are biologically immortal animals; a common cause of death is disease, not old age, and grow and reproduce...

To date, there’s only one species that has been called ‘biologically immortal’: the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle. A new jellyfish life begins with a fertilised egg, which grows into a larval stage called...
Hydra look a bit similar to the polyp stage of a jellyfish (which makes some sense, given that jellyfish and Hydraare grouped together in the phylum Cnidaria): a tubular body with a tentacle-ringed mouth at one end and an adhesive foot at the other. They’re very simple animals that spend their days mostly staying in one place in freshwater ponds or...
Lobsters also do not experience senescence. Unlike Hydra’s reliance on particular genes, however, their longevity is thanks to them being able to endlessly repair their DNA. Normally, during the process of DNA copying and cell division, the protective end-caps on chromosomes, called telomeres, slowly get shorter and shorter, and when they are too s...
There are many other animal (and non-animal!) species that offer tantalising glimpses into an ageless existence: the risk of dying for naked mole rats appears to not increase as they get older; the world’s oldest known non-colonial animal, a remarkably stress-resistant ocean-dwelling quahog clam named Ming, only died (accidentally) after a good 500...
Biological immortality (sometimes referred to as bio-indefinite mortality) is a state in which the rate of mortality from senescence is stable or decreasing, thus decoupling it from chronological age. Various unicellular and multicellular species, including some vertebrates, achieve this state either throughout their existence or after living ...
The so-called ‘immortal’ jellyfish, or Turritopsis dohrnii, can somehow reprogramme the identity of its own cells, returning it to an earlier stage of life. In other words, it can age in reverse and morph from an adult back into a baby.
Nov 28, 2017 · Some animals are what is known as biologically immortal - they don't ever appear to age and die. Can we learn from studying them? Georgia Mills spoke to Aziz Aboobaker from the University of Oxford...
They are, or we think they may be, biologically immortal. This means that, unless killed by a predator, disease or drastic changes to their environments, they can live indefinitely.
