Fish of the Week – Immortal Jellyfish

Welcome back to another fish of the week. Again, not a fish and I apologise in advance for false advertising but i think you’ll find the following winner of ‘Fish of the Week’ more than satisfactory.

Personally I’m a huge fan of sci-fi and fantasy and all the interesting concepts that can be found with in. Time travel, teleportation and distant worlds have long been familiar concepts of the genre that seem far-fetched and impossible to obtain (at least for the moment!).

Another such mythical ability is Immortality which until up to now, has appeared to be only obtainable by gods, annoying teenage vampires and Superman. Recent discoveries have revealed that we need to add another super being to this prestigious list in the form of a small jellyfish.


Let me explain,

In 1988 a budding young marine biology student was conducting research in Rapallo, Italy on hydrozoans. One particular species called Turritopsis dohrnii threw up some interesting results…it refused to die. The vexing jelly appeared to age backwards, growing younger and younger until it reached its earliest stage of development, polyp stage, at which point it began its life cycle anew.

Remarkably the discovery was barely noticed and it was thanks to jelly fish scientist Shin Kubota that this incredible discovered came about.

Human beings and jellyfish have are surprisingly similar genetically, which is why researching the immortal jellyfish is so important. With this it mind it is important to remember that humans also share about 50% of DNA with bananas…!

Many scientists think jellyfish are very different from humans and it for this reason convincing people to fund further research is  difficult.

The consequences of humans attaining immortality i will leave for the philosophers such as my good friend Ed, see his blog for a wide ranch of brain wrinkling discussions. For the mean time good dives everyone!


Stay Narked!
