  • a small jellyfish that once reaching adulthood, can transfer its cell back to childhood. It may do this process to live longer.
  • an 'immortal' jellyfish is swimming through the worlds oceans, according to scientists. The Turritopsis Nutricula is able to revert back to a juvenile form once it mates after becoming sexually mature. Marine biologists say the jellyfish numbers are rocketing because they need not die. The jellyfish originally come from the Caribbean but have spread all over the world.
  • This creature is the only known animal that is capable of reverting completely back to its younger self. It does this through the cell development process of transdifferentiation.
