What are the bears?
Water bears, also known as Tardigrady, are unique microscopic organisms that can be found in almost every environment on Earth. Despite the fact that they are widely distributed and show an incredible ability to survive in intense conditions, most people do not know much about them. If you have a microscope, you will probably find some local water bears. As he enlarged them, he observed a small creature in the samples of water, and called the bear's appearance and the bear's appearance. In high enlargement, these creatures really look remarkable like bears, although they have two other sets of legs and apparently segmented bodies. Their faces are also quite expressive and some beautiful prints of enlarged Tardigrads can be found in museums of natural history.
Some people call these animals moss nelata because they often occur in samples of lichen and moss. Scientists believe that bear bears are related to arthropods and annelids, a large phyl segmented blackscent. Adult Tardigrade has five body segments, including the head, along with four sets of legs. The legs have distinctive claws that appear remarkably well at magnification.
The thing that causes water to be remarkable is their ability to survive in extreme situations. These creatures can tolerate much more radiation than most other organisms can, and can also survive at extreme temperatures, high pressure areas such as hydrothermal ventilation openings deep below the ocean and in the vacuum of the universe. They can also be dehydrated until ten years without any bad effects. Tardigrady also seems to be able to deal with many environmental toxins.
Because of their amazing versatility, water bears can be found incredibly -resistant environments around the world. Scientists also performed tests with these resistant animals and subjected them to extreme pressure, intense colds and heavy exposureSurgery. The average water bear can take up to 570 times the amount of radiation it needs to kill a person.
water bears have another interesting feature; They are eutelic organisms, which means that mature adults retain the same number of cells throughout their lives. Once Tardigrade has reached maturity, growth is performed by cell expansion rather than cell division. A typical adult bear with water has about 40,000 cells in its body.
