What do water bears rely on to survive well in a variety of harsh environments?

Natural selection, the survival of the fittest gives it the ability. Water bears, commonly known as tardigrades and bear insects, are common names for tardigrades, and there are more than 900 species of recorded animals.

Extremely small, ranging from 50 microns to millimeters, the water bear is covered with a water film that protects the body from drying out and breathes oxygen from the water film, making it the most vital creature on Earth.

The "unkillable" tardigrades are genetic "thieves". As one of the most vigorous creatures in the world, the tardigrades can be traced back to the Cambrian period 500 million years ago, and after a long evolution, the tardigrades have become extremely small, with eight round fat legs, covered with a layer of water film, and they can be seen crawling under the microscope.

Although they are small, they can be found everywhere from the majestic mountains to the endless deep sea, from bubbling hot springs to Antarctic ice, and even in a vacuum, they can lay eggs normally.

Scientists have found that about 6,000 genes of the tardigrade are derived from other species, accounting for about one-sixth of its total genetic goals. They speculate that the miraculous abilities of tardigrades may be related to foreign genes. They are able to absorb a variety of molecules, including DNA, from the environment by dehydrating and regenerating by water absorption, and they are very good at repairing DNA and repairing damage caused by dehydration.

For the first time, Japanese researchers have successfully revived tardigrades that have been frozen for more than 30 years, which will improve the understanding of the mechanisms and conditions for the long-term survival of cryptozoans.

These hatched newborn pups are normal, free of defects and abnormalities. Electron microscope of tardigrades: When the tardigrades are dry or the environment deteriorates, they shrink into a barrel shape and quietly endure dormancy (cryptophytic), and they show amazing endurance.

It can survive in a frozen, boiled, air-dried state, and even survive in a vacuum or under radioactive rays. There are more than 900 species of water bears recorded, many of which are worldwide.

Relying on the water film on the water bear, it can keep warm well.

The water bear is covered with a film of water that is used to keep the body from drying out and at the same time breathes the oxygen in the water film, making it the most vital creature on Earth. In addition to this, there are also the genes of the water bear.

The water bear survives on the water film on its body.

Self-strong perseverance, and that strong physique.

Small in stature, good in stamina, good in water, doesn't seem to breathe much, born to live, simple.

The survival of the fittest, through the survival of the fittest, has adapted to this environment.

Small enough for the size and genes that humans haven't discovered yet.

Small in stature, suitable for all kinds of terrain, and low requirements for energy**.

I'm so small, no one can catch me! I've been able to hide from anyone, it's short, concise, and tenacious, and that's how it came about

Water bears have survived for a long time, and the outside world has little influence on their survival.

**Strong willpower developed by years of vigorous hair.

It is of great significance for human beings to study the life structure and super vitality of water bears, which are currently the most tenacious creatures in the world, and most importantly, there is no one.

If you want to ask who is the strongest species in the world, personally, the most tenacious animal in the world is the water bear, it is the first, no one dares to call it the second. Why? This is because the tardigrades have super comprehensive strength, cold resistance, radiation resistance, vacuum resistance, etc., and are almost invincible.

The tardigrades give people a cute feeling, the largest is only about a millimeter, and in such a small size, you have to use a microscope to observe this little guy. Water bears. As the name suggests, it looks a bit like a bear.

Water bears can adapt to almost all harsh environments, in the Himalayas at an altitude of more than 6,000 meters above sea level, there is also his shadow in the high temperature environment, there is also a presence in the extremely cold environment, in the deep sea 4,000 meters has also appeared, ** the more dangerous, they go there, they seem to be bent on death. But it backfired, and they all lived very well without exception, and they were not hurt at all.

In view of the characteristics of water bears, some people have done experiments, no matter in the extreme cold or ultra-high temperature, they are helpless, and they can't hurt them in the slightest.

Then try again what happens in the ultra-high atmospheric environment, and the result is the same, or nothing happens.

The discovery of these conditions shows that the tardigrade has super vitality and has become the best choice for people to study. Some people say that rats are very reproductive, and that humans will rule the world after that, so I laugh and say nothing, but when it comes to vitality, all other creatures have to stand behind in the net.

As the creature with the strongest vitality on this planet, the water bear is already an invincible existence, and there is no environment, ** and so on.

Without water, people can only survive for about 100 hours. But there is a creature that can live without water for decades. This one-millimeter-sized animal can survive in the hottest and coldest environments on Earth, and can even withstand high doses of radiation.

When the water bear is dry or the environment deteriorates, the water bear shrinks into a barrel shape and quietly endures dormancy (cryptophytic phenomenon), and at this time, it shows amazing endurance. It can survive in frozen, boiled, air-dried conditions, and even in vacuum or radioactive rays.
