Meet the Turritopsis dohrnii, also known as the "immortal jellyfish", which has a remarkable ability to reverse its ageing ...

Almost by chance, researchers in Norway found adult comb jellies reverse their development and become larva again when stressed by starvation. It helps them survive because larva eat less than the ...

They found that when adult Turritopsis dohrnii jellyfish were stressed, they reverted to an earlier stage in their life-cycle — rather than die. Normally, the adults (medusae) release a free-swimming ...

Turritopsis dohrnii follows a typical jellyfish life cycle, beginning as a larva and maturing into a polyp and then an adult ...
