These earthly creatures are really immortal!
Eternal life was and remains an idea of a fix for mankind, who still has not lost hope of finding the elixir of youth, which endows the ability not to age and prolongs life to infinity. Meanwhile, on Earth there are undying beings who have received their immortality from nature. Who they are, you will learn from our article.
Plants and creatures with immortality
Among the creatures that claim to be immortal, the first place is occupied by the jellyfish, which scientists gave the name Turritopsis nutricula. After going through the full life cycle, she manages to reverse the aging process, starting anew the countdown of her existence.
Most jellyfish death occurs after mating. After that, the immortal jellyfish, on the contrary, begins to rejuvenate - it returns to the juvenile stage and lives life anew.Juvenile stage - the period of postembryonic development, which lasts until the end of puberty. Wikipedia
The fact is that Turritopsis nutricula has two phases of the life cycle: existence in the form of a polyp and the actual jellyfish. After reaching puberty, this inhabitant of the sea depths turns into a polyp, from which young individuals bud. This process is cyclical and can be repeated countless times. Moreover, falling into unfavorable conditions that threaten its existence, the immortal jellyfish also changes shape, becoming a polyp and waiting in such a way that the environment surrounding it becomes more comfortable.
In other words, this hydroid intestinal cavity never dies by its death, and its life can be interrupted only by killing.
The Italian Fernando Boero discovered this amazing feature at the end of the last century, and it happened quite by accident. He conducted experiments on Turritopsis nutricula, but not achieving the desired results, for some time postponed research. Because of the absent-mindedness inherent in scientists, he forgot to replenish the water in the aquarium, and he finally dried up.
Deciding to prepare the container for the following experiments, Boero began to clean the aquarium, discovered the remains of the experimental material and decided to investigate it at last.What was his surprise when it turned out that the jellyfish did not die, but survived the transformation into larvae. The scientist poured water into the aquarium again, and after a while he noticed that the larvae had turned into polyps, and medusks began to appear from them.
The scientific world immediately took up the study of this phenomenon. It turned out that the secret of vitality of these hydroids lies in the composition of their cells, which are actually analogs of human stem cells.The article in the topic: "Stem cells - a panacea for all diseases?"
There are other inhabitants of our planet, whose existence lasts immeasurably long. About who else is granted eternal life, see the video:
After studying the immortal jellyfish, scientists said: eternal life is possible, but for humans - only in theory. Studies in the field of genetics are still at an early stage, and no one undertakes to predict when humanity will get a chance for immortality.Immortality is a hope that should be seduced.Anatole France
5 animal old-timers of the planet
If eternal life is an unattainable dream for us, then longevity is considered as a long-term, but very realistic perspective.In the meantime, we can only envy animals whose age has passed for a hundred years.
Killer Whale Granny
The youngest of all the old-timers lived just over a century. By the way, scientists have determined the age of this mammal by the number of offspring, because it is known that killer whales become sexually mature at the age of 14, stop giving birth at 40, and live to the end of their days as a “family”.
Lobster weighing over 9 kg was caught off the coast of Newfoundland and lived for some time in one of the New York restaurants. The restaurateurs simply did not raise a hand to kill an arthropod whose age was 140 years. A year later, under pressure from animal defenders, the lobster was released.
115-year-old reptile lives in one of the reserves in New Zealand. Despite his venerable age, six years ago, Henry became a father. His "wife" at that time was 111 years old.
The inhabitant of St. Helena recently turned 182 years old. He became clumsy, sees almost nothing and almost lost his scent, but still he hears well. Today, this turtle is considered the oldest reptile of the planet.Prior to that, the palm was her relative from India: the giant turtle Advaita, who lived in the Calcutta zoo, died at 250 years of age.
This 500-year-old mollusk was fished around the Icelandic shelf. Scientists first stated that he was born in the 17th century, but having carefully counted the number of arcs on his shell, they increased the age by one century.
Of course, this is not eternal life, but, you see, to live for half a millennium is also not bad.
