Why are invertebrate tardigrades a biological wonder ?

Because this animal is a relatively long-lived animal on earth, it can survive in all kinds of environments, and it will not die even in a vacuum. And it's also a hermaphroditic creature.

Because tardigrades have super survivability, they can survive in extreme cold or hot boiled conditions, as well as in vacuum states or radiation, and in extremely harsh environments, water bears will also reduce their body water content to 3% through "cryptophytic" methods

Because no matter how bad the living environment is, it has the ability to survive, and it has the ability not to die at low temperature and freezing, and it is not afraid of radiation, and it can not die in a vacuum. And it can be resurrected in a dehydrated environment, can it not be called a miracle?

Because the life force of the tardigrade is very tenacious, even if it is thrown into space, it can still survive for a long time, so it can be called "a great miracle of the biological world".

It's true. Because this bug is very ancient, and this bug has a strong vitality, no matter in any harsh environment, he can survive very well. That's why it's called the most tenacious creature that can't be killed.

It is true that the vitality of water bears is very tenacious, they have a high tolerance for bad environments, and they have a high ability to survive against severe cold, drought, and high temperatures, so they are called the most tenacious creatures that cannot be killed.

It's true. Water bears are able to survive in extremely harsh conditions and slow down or stop their metabolic activity for long periods of time, thus keeping themselves alive or even immortal.

Known as an immortal creature, how tenacious is the life force of the tardispeller?

The tardigrade is best known for its ability to kill no matter how hard it is, and it is the most tenacious creature on earth.

Water bears belong to a small aquatic animal, their body length is generally about one millimeter, the long can reach millimeters, the short one is only 50 microns, so under normal circumstances, humans do not notice them at all, and the small water bears can only be observed with a microscope.

Despite its small size, the water bear seems to be an insignificant existence to other animals, but its tenacious vitality is amazing, and it is known as the most tenacious animal in the world.

In addition to the existence of water bears in ordinary environments, they are also widely found in extreme cold and extremely hot environments, including minus 60 degrees Celsius under the ice layer of 5 meters in Antarctica, volcanic hot springs with high temperature and high heat, and even in the deep sea with huge water pressure of more than 4 kilometers, and the Hima Zhongwu Qianraya Mountain at an altitude of more than 6,000 meters, and they live a moist and happy life.

After the discovery of the tardigrades, in order to test the life endurance of the tardigrades, the tardigrades were put under a high temperature of about 180 degrees, and the results of this insect can survive well for a few minutes, and it will not be affected by about 150 degrees.

After putting the tardigrades at a low temperature of minus 200 degrees, the tardigrades entered a state of frozen dormancy, and scientists still succeeded in resurrecting the tardigrades 32 years later, indicating that the tardigrades can tolerate low temperatures of minus 200 degrees.

In 2007, scientists sent water bears into orbit through spacecraft and exposed them to a vacuum, where they were exposed to radiation levels high enough to burn people to ashes. Amazingly, 1 3 of these tardigrades have come back alive, and 1 10 of them are able to reproduce normally after they are released into the Earth's environment.

Summary. Water bear (scientific name: tardigrade, alias: water bear) is a heterotardigrade of the phylum tardigrade. This group of animals is found all over the world.

The water bear is extremely small, ranging from 50 microns to millimeters, and has 4 pairs of short and thick appendages, which have claws at the ends of the appendages and are slow to move; The body surface has epidermis and periodically shed, the ventral surface is flat, the back is raised, and there are 4 pairs of clawed legs on both sides, which slow down the movement by crawling; Dioecious, oviparous, directly developed, a small amount of water bears are present in activated sludge. It has a strong tolerance for adverse environments.

Do tardigrades have a spine.

Hello, I am inquiring for you, please wait a while, I will reply to you immediately Dear, hello, I am happy to answer for you. Water bears do not have a backbone.

The water bear (scientific name: tardigrade, alias: water hall bear insect), tardigrade, heterotardigrade.

These animals are found in all parts of the world.

I hope the above is helpful to you If you are satisfied with me, please give me a thumbs up

Human beings are undoubtedly the most advanced beings in the theory of evolution, and their intelligent brains have given us to create civilization on the earth, but human life is also fragile, and its physical strength is inferior to that of many animals.

For example, humans need to wear thick spacesuits and bring oxygen to conduct research in space.

Speaking of which, there is a cute-looking species that can survive in space where the temperature difference between day and night on the surface is greater than a few hundred degrees Celsius. It's called a tardigrades. Not to mention the lack of oxygen**, extreme cold, high temperature, high pressure, and ultra-high radiation.

It can be carried down, survive in a vacuum, and reproduce and lay eggs. It's really a burst of vitality.

The tardigrades are creatures in the phylum Tardigrades that existed in the Cambrian period 500 million years ago. It is a multicellular organism that grows very small, mostly between tens of microns and hundreds of microns, so if you want to see a tardigrade, you have to use a microscope to see it. They have eight fat legs and are covered with a film of water, so named for their bear-like appearance, and are translucent, but change color depending on the color of the food they eat.

That's what makes them survive in such brutal living conditions, it's because of it.

Under these conditions, the skin capsule shrinks, and the body water accounts for only 3%, which looks like death, but in fact, when the time is right and the environment changes enough for them to survive, they will begin to wake up, reproduce, survive, break the state of seclusion, and come back from the dead!

The tardigrades are actually a creature, but because they are small, they have a strong vitality, which makes them look so unique.

Water bears are the common name for the animals of the phylum Tardigrades, with nearly 1,000 species. It is unique in that it can survive both high and extremely low temperatures without dying.

Water bears, also known as tardigrades, are a common name for tardigrades, with more than 900 species recorded.

The organism is small at 50,144 microns and can only be seen with a microscope, and its body is covered with a film of water that protects the body from drying out and breathes oxygen from it.

Considered one of the most tenacious creatures, tardigrades can be found in mountains, hot springs, glaciers, and deep seas.
