Some Amazing “Immortal” Living Beings You Should Know!

Discovery Dec 16, 2021

For some years now, humanity has wondered if it is possible to live forever, or at least if it is possible to extend our lives. Believe it or not, there are some living beings on our planet that are capable of living for many years and withstanding the most extreme conditions. Let’s talk about some of the most interesting creatures on the planet.

A biologically immortal jellyfish

There is a species of jellyfish that is considered immortal. We are talking about the Turritopsis dohrnii, a type of jellyfish found in the Mediterranean Sea. This species has an incredible ability: it is capable of reversing its age and regressing to a sexually immature age.

This form of "rejuvenation" allows the jellyfish to rebuild its cells in the event of injury or illness. The Turritopsis dohrnii jellyfish is one of the few animals discovered with this ability, which is why it is considered “immortal”.


Human beings, as well as most of the species on this planet, are vulnerable to environmental conditions. By ourselves, we cannot withstand high temperatures, or sub-zero temperatures, for example. This does not happen in the case of tardigrades.

We are talking about tiny animals (half a millimeter) capable of withstanding the worst environmental conditions. This animal can survive in environments with more than 150 ° C, or environments at -200 ° C. It is also capable of surviving in space and can withstand over 6000 atm of pressure.

Turtles and lobsters

In the animal kingdom, few species can live for more than 100 years. However, in the case of turtles and lobsters, 100 years of age is half their life. Both species are capable of surviving many years and usually only die when they receive a serious injury or illness. For example, the oldest recorded turtle was born in 1832 and is currently 190 years old.
