What creatures in the world can t die? Which creatures are immortal

There are no undead creatures, it's common sense.

Bacteria. Enough is common.

The most mysterious creature in the world, with an immortal body, can't die no matter how you kill it, it's amazing!

Creatures that never die are: tardigrades, lighthouse jellyfish, planarians, rotifers, turtles, etc.

1. Water bears

Under harsh conditions, tardigrades will enter a state of suspended animation, do not eat, drink or die, and return to normal after safety, and can survive in boiling water, solid ice, radiation and vacuum environments.

2. Lighthouse jellyfish

The lighthouse jellyfish is a representative of immortality, and the secret of its immortality lies in the differentiation process of stem cells, which can be continuously regenerated.

3. Planarians

The insect bypasses the aging process by regenerating an enzyme that spoils during DNA repair and allows the head to grow back.

4. Rotifers

Rotifers have cryptophytic properties. When environmental conditions deteriorate, such as when water bodies dry up and the temperature is not suitable, they can stop their activities as if they were dead, and their metabolism is basically absent. When the environment improves, they will recover again.

5. Sea turtles

Sea turtles do not degrade over time like other animals and can live for centuries.

nutricula), most likely the only creature in the world that does not die.

According to scientists, the diameter of the "lighthouse jellyfish" is only 4 5 millimeters, but it is such a very tiny creature that has a magical ability to "rejuvenate". According to reports, normally, jellyfish will die after reproducing the next generation, but after the "lighthouse jellyfish" reach the stage of sexual maturity, they will return to the young stage and start another life process, and theoretically, this cycle process is repeated again and again and can be repeated forever.

<> "Are there truly immortal creatures on Earth?"

Undead? Of course, all of the creatures we mentioned above are long-lived but have a lifespan limit, and in nature, there is really one creature that can achieve "immortality", and that is the lighthouse jellyfish (turritopsis nutricula).

The lighthouse jellyfish is a kind of jellyfish in the family of Hydra flowers, originally it was a small jellyfish that could not be seen clearly by the naked eye, with an average diameter of only about a millimeter, but scientists could not study it, because this product was "fine".

Lighthouse jellyfish are extremely difficult to accomplish true immortality.

Although the lighthouse jellyfish has the ability to defy the sky, it is still far from the real immortality, first of all, under normal circumstances, the lighthouse jellyfish will reproduce sexually, and then die normally. Secondly, although in extreme cases, they can become many "little lighthouse jellyfish" like Sun Wukong plucking a handful of monkey hair and blowing, but only a few of these lighthouse jellyfish can live. Therefore, even lighthouse jellyfish with the ability to "rejuvenate" will not be overflowing, and they will not be able to achieve true "immortality".

Why doesn't there exist a true undead on Earth?

First of all, this creature is invincible on the earth, because no creature can harm it, not even a virus (a virus is not a creature), and it is still an immortal shirt, which is amazing, once this creature appears, the number will soon increase. Secondly, the growth of the number of ** will bring a problem, that is, the consumption of resources, because the earth's organisms are all carbon-based organisms, all need nutrients, and before the emergence of this kind of organisms, the organisms in nature are mutually restricted, but after its appearance, this balance is broken, they can use the number to crush other organisms, and eventually occupy all the ecological niches on the earth.

The basic structural unit of an animal is the cell, and every cell must be metabolized, and the number of metabolisms is limited, so you can say that a creature is very long-lived, but it is definitely not that it will not die, and the individual prehistoric frogs that you have heard of in the ground have only hibernate to reduce their metabolism to a very slow extent, but for a long time.

In the end, he could not escape death.

Dragon Phoenix Unicorn Mythical Animals Will Never Die 2007-02-16 03:39:38 Added:

I have listed three kinds of them, and they are logical, because in reality, as long as it is a living thing or a life, it will die, including the so-called "Polar Ice Worm", as he said, as long as the earth warms, the earth's crust moves, or volcanic eruptions will cause the so-called "Polar Ice Worm" to die, so no living thing will not die, unless it is a mythical animal, the dragon and phoenix, the unicorn.

I think unless all life on Earth is exterminated.

All living things do not die. Didn't all plants and animals evolve from primitive single-celled organisms? There should be a little bit of the genetics of a single-celled organism. Future plants and animals will also evolve from existing evolution.

So it's going to go on forever. But it looks like you've got the right answer.

I hope to be able to post it and share it with you after the time has passed. Person. Pig.

Cattle. Because life is endless.

The Distinction Between Creatures and Dead Things Creatures, there is life, but there is an end Dead things, no life, 1) living things after death and after death 2) Human beings are all dead things, so to speak, they will exist forever.
