7. Turritopsis Dohrnii – Immortal
Unlike the Hydra, who can divide its cells effortlessly, this jellyfish’s cells can transform into different kinds of cells, depending on what it needs. It can also go back to its polyp stage to heal an injury, and then grow into an adult jellyfish again.
8. Water Bear aka Tardigrades – Immortal
These cute little microscopic life forms have existed on Earth for around 530 million years. Tardigrades can literally stop living thanks to the process called cryptobiosis. Also, their cells don’t divide as they age, they just get bigger. Nature, you’re crazy!
