Hydra – Immortal
We have to admit that we feel a bit envious of the Hydra. After all, this minuscule organism lives forever without showing signs of deterioration or aging. It only dies when it has a disease or gets eaten by a predator. A study even said that “an individual hydra can live forever under the right circumstances.” They have way too much power for such a tiny animal! This invertebrate is known for its cylindrical body and small tentacles from one end of the body. It only grows to be 10 millimeters or 0.4 inches long.
The Immortal Jellyfish – Forever
How do you feel about the prospect of living forever? Well, you might want to switch places with the immortal jellyfish. Its scientific name is the Turritopsis dohrnii. This is easily one of the most intriguing animals in history. Did you know that it ages in reverse? They grow from a polyp into an adult jellyfish, only to revert back to an infant! Yes, it is pretty much a marine version of Benjamin Button.
