Turritopsis dohrnii are tiny - less than 0.2 inches (4.5 millimeters) across - and are eaten by other animals such as fish or may die by other means, thus preventing them from actually achieving immortality. The jellyfish, which are native to the Mediterranean Sea, can repeat this feat of reversing their life cycle multiple times and therefore may never die of old age under the right conditions, according to the Natural History Museum in London. Mature Turritopsis dohrnii are special in that they can turn back into polyps if they are physically damaged or starving, according to the American Museum of Natural History, and then later return to their jellyfish state.

These polyps then produce free-swimming medusas, or jellyfish. Jellyfish start life as larvae, before establishing themselves on the seafloor and transforming into polyps. Turritopsis dohrnii are called immortal jellyfish because they can potentially live forever.

The age estimates came with a degree of uncertainty, but even the lowest estimate of 272 years still makes these sharks the longest living vertebrates on Earth. The biggest shark in that study was estimated to be about 392 years old, and the researchers suggested that the sharks could possibly have been as much as 512 years old, Live Science previously reported. Lawrence Shark Observatory in Canada.Ī 2016 study of Greenland shark eye tissue, published in the journal Science, estimated that these sharks can have a maximum lifespan of at least 272 years. They can grow to be 24 feet (7.3 meters) long and have a diet that includes a variety of other animals, including fish and marine mammals such as seals, according to the St. Greenland sharks ( Somniosus microcephalus) live deep in the Arctic and North Atlantic oceans.
