Check out an animal that lives forever and never dies

There is an animal that can live forever on earth. The animal comes from the jellyfishes. Its specie name is Turitopsis Dohrnii. It lives in the tropical and temperate waters across the globe.


Turritopsis dohrnii, also known as the immortal jellyfish, is a species of small, biologically immortal jellyfish found worldwide in temperate to tropic waters. It is one of the few known cases of animals capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual. Others include the jellyfish Laodicea undulata [sv] and species of the genus Aurelia

Fully grown, Turritopsis dohrnii is only about 4.5 mm (0.18 inches) across, smaller than a pinky nail. A bright-red stomach is visible in the middle of its transparent bell, and the edges are lined with up to 90 white tentacles. These tiny, transparent creatures have an extraordinary survival skill, though. In response to physical damage or even starvation, they take a leap back in their development process, transforming back into a polyp. In a process that looks remarkably like immortality, the born-again polyp colony eventually buds and releases medusae that are genetically identical to the injured adult. In fact, since this phenomenon was first observed in the 1990s, the species has come to be called “the immortal jellyfish.”


An adult jellyfish is known as a medusa. Jellyfish belong to a group called Cnidaria, which also includes sea anemones and corals. As animals, they are subject to the cycle of life and death - though one species is known to bend the rules

Their tentacles retract, their bodies shrink, and they sink to the ocean floor and start the cycle all over again. Among laboratory samples, all the adult Turritopsis observed regularly undergo this change.


And not just once: they can do it over and over again.


Thus, the only known way they can die is if they get consumed by another fish or if a disease strikes the jelly.


T. dohrnii may bend the rules to rejuvenate itself, but it can't always cheat death. For example, jellyfish, including immortal ones, are prey to other animals, such as fish and turtles. Polyps are also practically defenceless to predation by animals such as sea slugs and crustaceans
