When you think of immortality, what comes to mind? For me, I imagine vampires, Voldemort, and gods from mythology. But never would I have imagined that the embodiment of immortality would have been none other than the humble jellyfish.
Turritopsis nutricula is a species of hydrozoan (jellyfish) that is capable of a process named transdifferentiation. This means that after becoming a mature “adult” jellyfish, it can regress back into its infant stage, known as its “polp” form.
The majority of jellyfish species only have lifespans ranging from a few days to a few months. Natural selection has allowed this marvelous creature to theoretically live forever as long as they aren’t eaten or overcome by disease. But this presents a bit of a problem. With an immortal jellyfish roaming around, scientists fear that they might clog the ocean. These types of jellyfish reproduce constantly, so, what is stopping them from taking over?
Its a bit of a scary thought, but these jellyfish do provide some benefits to the world. The process of transdifferentiation has inspired scientists to find a method of mending damaged or dead tissues in the human body using stem cells. Who knows, this little creature could be the key to curing cancer and preventing aging!
Omg Richard! You actually joined! How is it? Maybe I should join too…

You should Eva! So far it has been lots of fun. :]
Very insightful, Richard. I only wish I could own one of these
