Many of the animals in the seas, skies, and earth live long lives. Yet the oldest living creature in the world is an immortal jellyfish that has never died. Its family name is Turritopsis Dohrnii. It hails from a class of small animals that live mainly in saltwater.</p> <p>The Dohrnii begin their life journey as larvae with a diameter of no more than 4 millimeters. The larvae have a tiny vase-shaped body with a mouth surrounded by tentacles. They come together and attach themselves to the ocean floor. Soon, they mature into jellyfish. Once they mature, they travel great distances and hunt other fish for food. The Dohrnii has currently spread across three continents by hitchhiking on the underside of cargo ships. Due to their tiny size, the countries they are invading are unaware that it is even happening.</p>
