The tardigrade is a microscopic animal that lives in the aquatic environment. With dimensions of only one and a half millimeters, the tardigrade is very tenacious. In addition, it is quite common, because it can be found in any climatic zones. It is called a water bear, although the bear does not differ in such vitality. It perfectly tolerates low temperatures and can withstand up to -273 and + 151 degrees Celsius. Radiation is also unaffected by it: it withstands the maximum indicators for other organisms, increased by 1000 times. In 2007, scientists carried out an experiment. In complete vacuum, the tardigrade was placed in low orbit when they returned to Earth, surprising but true - everyone was alive.

The most important feature of this small fish is its lungs. They make it possible for her to survive for a long time without water, and this period can last up to a year. In a drought, the lang fish buries itself in the mud and hibernates; it can stay like this for a whole summer without nutrients and water. There is a story that unwittingly became an experiment when a lang fish placed in a box with mud was accidentally lost. Six months later, this box was found, but the dirt in it was dried up. When the mud was diluted with water, the fish was alive.

Very similar to the immortal jellyfish. Scientists have not yet fully studied the vital features of the hydra. But it is absolutely known that the structure of the hydra consists of special chambers that constantly die off and are replaced by new ones. Thus, destructive substances do not accumulate in the body and any fatal flaws are excluded. Therefore, the life cycle of hydras is also endless.

Turritopsis nutricula is considered an immortal jellyfish and fully lives up to its nickname. And the reason for this is an infinite number of ripening cycles. That is, this creature is constantly, as it were, born anew. Again and again after the end of the maturation period, the jellyfish reverts to the polyp stage and begins to mature.
