Turritopsis nutricula, the invasion of the immortal jellyfish
We are before an invasion in all rule. Quiet, slow, invisible, but for that reason less nonreal. And it is happening now, in front of our own noses and in all the oceans of the planet. The invader is a small jellyfish, hidrozoo of just half centimeter of length, but with a characteristic that animal makes unique between all the creatures of the kingdom. In fact, of a form that Science not yet has managed to include/understand, the Turritopsis jellyfish nutricula is immortal.
Unlike the other jellyfish (and of the rest of the animal) Turritopsis nutricula does not die after reaching its adult state, but he is able to rejuvenecer , to return to his youthful form and to repeat his vital cycle until reaching one second maturity and one third, and one fourth, and thus to a number of times that is, according to the scientists, potentially infinitely.
Nutricola Turritopsis is able to secure this feat because the way is shortage to modify its cells once these have been different. And to make them back down to phases previous to its specialization. Transdiferenciación is a called phenomenon that can be seen, for example when a damaged organ regenerates its weaves. Nevertheless, for this species of hidromedusa the process is something current in its vital cycle.
In laboratory tests, the one hundred percent of the units of T. nutricula analyzed has matured and returned to youth tens of times, without losing in those changes not one of their characteristics or capacities. The investigators had to reach the conclusion that the organic death is something that in this species, simply, does not happen.
Mystery without solving
The existence of this exceptional creature is known for more than one decade. From the Nineties the species has been put under genetic and biological analyses of all type to try to start to him, without success, the secret of its immortality.
But the alarm voice was not given until the past summer by the bióloga Maria Pia Miglietta, of the Pennsylvania State University, that indeed because of a series of realised genetic analyses to tens of unit of the jellyfish realized which the species, original of the seas of the Caribbean, had practically extended by all the oceans of the world.
What is able to make this jellyfish, affirms the investigator, is equivalent to a butterfly that could return to become a caterpillar . In its analyses, Miglietta compared the mitocondrial DNA of units of Turritopsis picked up in Florida and Panama with others coming from other places of the world and that had been collected during previous investigations.
And this comparison went when doing when it was with the surprise that determined genetic sequences they were repeated in units obtained from Panama to Japan. In fifteen of them, coming from both countries and of the epañolas and Italian coasts, the sequences were identical. The existence of this landlord implies an extraordinary facility of movement. And the investigators think that facility, just as the one of many invading marine species, comes from the warehouses and the ballast tanks of the boats that sail by those waters. The one hundred percent of the studied units matured and returned to youth in tens of occasions.

that is not absolutely truth
that the cycle begins again if but total, she looks for her destruction.
Ladies and gentlemen, have spoken the Great Felipe, expert and recognized specialized marine biologist in immortal jellyfish who says that that is not absolutely truth . Jajajaja
If it is a inmotal jellyfish, abra a marine invasion of jellyfish?
Q excrement you say? you are all idiots? or it only seems it?
It does not look for its own destruction, and he is not an invading enemy!
Duh!
immortal jellyfish ke crazy that does not assume that all the alive beings must die one of the requirements to be servivo is to die. that no?
Apparently reason why they say the studies is biologically immortal. Clearly many by diseases, used like food, etc. die.
But in its natural cycle of life, theory podria not to die of oldness. That is intriguing, but I create lack deep studies but to affirm it. After all this species one has studied does very just a short time, and reason why I infer the unit but longevo tendra about 10 years of life.
