  • Scientists have discovered a new species of marine invertebrate that breaks the traditional cycle of birth, ageing, and death.
  • They are also known as ctenophore Mnemiopsis leidyi, can defy age and revert to younger versions of themselves.
  • The adult comb jelly can regress and reach a larval stage if they are subjected to extreme stress.
  • Comb jellies could also be one of the first animals to have existed as their origin can be traced back to an estimated 700 million years ago.
