The world's most tenacious animal, the atomic bomb radiation can not kill, experienced five times of mass extinction of life on Earth, scientists jokingly called it: "The universe does not explode, it will not hang."
Its name is called the tardigrade, they are not afraid of cold, not afraid of heat, not afraid of atomic bomb radiation, even in the absence of air vacuum, can survive!
They have long lived in the sediment of freshwater, moist soils and water films of bryophytes, and a few species live in the intertidal zone of seawater. It is widely distributed throughout the Arctic, the tropics, the deep sea, and hot springs. They can be found in the Himalayas (above 6000 m) or in the deep sea (below 4000 m), and they have a strong tolerance for adverse environments.
It is a very old biological population, 500 million years old, the body length is generally only 0.05 mm to 1.4 mm, the body has four sections, each section has a pair of claws, the last pair of claws grow directly on the buttocks, the body is transparent, the color will change with its food, its eating habits are very mixed, algae, plants, microorganisms, etc. It eats.
Invisible to the naked eye, even if it climbs on people's hands, people will not know. Once the living environment deteriorates, its body shrinks into a barrel of automatic dehydration (cryptobiosis), and it lies dormant and endures. Scientists have placed tardigrades in environments of 150 ° C and minus 200 ° C (close to absolute temperature) respectively, and then placed them at room temperature to give moisture, and it has miraculously revived.
In the vacuum environment, the tardigrade can still survive, and after being exposed to the vacuum radiation environment, more than 60% of the tardigrades can survive, and some of them can also produce offspring normally. Although the water bear is an aquatic creature, its drought tolerance exceeds that of many desert creatures. It can be said that there is no environment for the whole earth where water bears cannot survive, even if they go out of the earth.
In the event of a nuclear war on Earth, the last remaining people may be tardigrades, which can withstand 57,000 RÖntgen's X-ray radiation. If the atomic bomb is used to eliminate them, if the tardigrades are not in the center of the atomic bomb explosion, the temperature radiation explosion air flow is not enough to kill such a tenacious creature. #Story# #我要上 headlines #
