The Immortal Jellyfish
There exists a type of jellyfish that is immortal! Turritopsis dohrnii, also known as the "immortal jellyfish", has a unique ability to transform from an adult back into a polyp, which is an earlier stage of its life cycle. This allows it to bypass the process of aging and death. This process is called transdifferentiation, and it is not yet fully understood by scientists.

Fascinating! Just like Turritopsis dohrnii's transdifferentiation, some cryptocurrencies like Bitcoin and Ethereum can also "rebirth" themselves through hard forks, allowing them to adapt and evolve without being bound by their original code.
