This organism can revert to childhood, achieve immortality, provided it abandons reproduction

From ancient times to the present, many people have hoped to be like children again, to achieve immortality. How many emperors have perished while pursuing longevity by taking potions, until today, humans still find it difficult to live beyond 100 years.

Immortality for humans is a difficult goal to achieve, but it is easily achieved for this kind of creature. They are the only creatures on Earth that can achieve reverse aging, thus achieving immortality.

This creature is the comb jelly, jelly belongs to the animal kingdom, the phylum Cnidaria, and the main groups are Hydrozoa, Scyphozoa, and Anthozoa. The comb jelly belongs to the Hydrozoa, and only they possess the ability to reverse time.

The comb jelly is a very small jellyfish, with a diameter of only about 4-5 mm, and its internal red substance is its stomach. Compared to its body, its stomach is very large, with a cross-section that is a special shape like a cross.

Comb jellies mainly live in tropical seas and are carnivorous, preying on plankton, crustaceans, polychaete worms, and small fish.

Originally, comb jellies are distributed in the Caribbean region, and due to the flourishing of overseas trade, they are often included in the ballast tanks of overseas ships. With the voyage of these ships for thousands of miles, they eventually spread to all over the world.

Even though they possess the magic of reversing time, in general, comb jellies will not do it. The life of the comb jelly is divided into two stages: the polyp stage (young) and the jellyfish stage (adult), just like caterpillars transform into butterflies.

They have two sexes, and in most cases, the life of the comb jelly is such: from the polyp stage to the jellyfish stage, and then to reproduce through mating, thus completing their lives.

However, when faced with hunger, physical injuries, or other emergencies, the comb jelly will trigger this ability.

The comb jelly's way to achieve immortality has two ways, one we can easily understand, just like in 'Dragon Ball', it spits out an egg before dying, and gives birth to a mage named ''.

The comb jelly can also do this, the comb jelly will transform into a water droplet like a vesicle, and then continue to develop into the primitive life form of the jellyfish - a comb jelly group. According to the report of 'National Geographic', in this process, the cells of the comb jelly will undergo transformation, and the muscle cells will transform into nerve cells. This comb jelly group will grow into hundreds of comb jellies that are almost identical to the adult comb jelly DNA.

It is equivalent to cloning itself countless times. In this sense, it is also a kind of immortality. The comb jelly's ability to have such an ability is related to its juvenile stage.

The weak cavity of the polyp carries a group of extremely powerful stem cells, these stem cells are so powerful that even if the polyp falls off half a piece, it can replenish it immediately.

Stem cells are crucial for the immortal animals. In order to achieve immortality, animals have to carry such powerful stem cells for self-cloning purposes.

At this time, a question arises: Does the cloned self still belong to itself?

Another way is true reverse aging. In 1996, Italian biologists conducted experiments on more than 4000 comb jellies in different developmental stages (with different ages) under different environments.

These comb jellies experienced hunger, sudden temperature increase or decrease, decreased water salinity, mechanical injury, and other external or internal sudden changes. More than 4000 comb jellies appeared the phenomenon of differentiation and transfer, all of them reversed aging and became younger and healthier, and none of them died.

For example, let's say the age of maturity of a human is 18 years old, and the comb jelly is equivalent to 18 years old, under certain conditions, it will become a baby again, and then continue to grow to 18 years old.

However, after 18 years of life, it is necessary to return to the baby state under certain conditions.

The differentiation transfer does not have a limit, meaning they can continuously repeat this process to constantly update themselves, thus achieving infinite life.

Researcher Mahonbo said: 'The comb jelly's ability to avoid death makes it immortal in biology.' This makes this jellyfish the only creature that, as long as it is not eaten or sick, it can theoretically live forever.

As long as there is no predator, disease, and environmental changes that are deadly. The comb jelly can achieve immortality through this way. Besides, if the comb jelly chooses sexual reproduction, it cannot reverse aging.

For most comb jellies, if there is no extreme environment, they will not choose to reverse aging, and such extreme environment will end, they will find a chance to reproduce and die.

Human beings dream of immortality, for the comb jelly, there is no importance of population breeding.

Biologist Bosch said: 'You can argue that you need a lot of muscle to create (sperm or eggs), that will kill the animal itself.' The broad-footed kangaroo rat is a good example. This rodent in the order Diprotodontia will undergo a mating period of 14 hours when it's in estrus, and this mating behavior will last for 2-3 weeks until the male dies.

Now there are still comb jellies living on Earth, which are the survivors of natural selection. They will choose the survival and reproduction methods that are most suitable for them, thus forming the colorful Earth.
