No brain, no stomach, no central nervous system, no respiratory system, no circulatory system...You would think jellyfish would be weird enough creatures. But nope. One species has taken "freak" to a whole new level with the ability to be, well, immortal.
Meet Turritopsis nutricula, better known as the immortal jellyfish -- and sometimes known as the Benjamin Button jellyfish because of how it transforms itself from mature adult back into baby form in times of stress or injury. Yep, this species of jellyfish has the ability to revert completely back to its polyp stage after reaching maturity. Essentially, the medusa, or mature form of the jellyfish, can transform into the polyps of a new polyp colony in a process is …show more content…
Another metaphor is a chicken that transforms into an egg, which gives birth to another chicken. The anthropomorphic analogy is that of an old man who grows younger and younger until he is again a fetus. For this reason Turritopsis dohrnii is often referred to as the Benjamin Button jellyfish.
Essentially a mature individual can transform itself into polyps, or a whole bunch of baby jellyfish. This cycling through of the stages of life is why it is called "immortal." However, while mind-blowing, we have to keep at least one foot in reality here. While theoretically this process can go on indefinitely, the fact is most individuals of the species do actually die, and there is no laboratory evidence showing continuous generations created in this strange way.
Okay, so Turritopsis nutricula is not exactly immortal as in it has been alive forever and will be alive forever. But it does indeed have the ability to reproduce in a, well shall we say immortal-like way that no other known creature can. Could the jellyfish hold the key to actual immortality? That is still up for
