Circle Of Willis: Anatomy, Diagram And Functions. Well, an eight-legged bear from your nightmares is more accurate. Tardigrades live in more places on Earth than humans do, so practically any handful of water has a chance of containing some. They can also survive extreme conditions—even exposure to the cold vacuum of outer space—and their DNA can withstand a battering by X-ray radiation. Many researchers have gone to extreme lengths to test tardigrade resilience, by blasting them (in their tun state) into space. Perhaps, mother nature does it to balance things out. Tardigrades are probably the most paradoxical animals on the planet. Humans, the intellectually dominant and technologically advanced species on the planet, can’t possibly be outshone by another.

There have been no species of Tardigrade found yet, that is involved in spreading diseases. That protects the membranes, proteins and DNA from being shattered, pierced and torn when cells become desiccated, according to a 2017 study in the journal Molecular Cell. The tiny little bodies of these mushy bears are a container of biological brilliance and a storehouse of superpowers that help them withstand conditions that would spell certain death for other organisms. Scientists have reported tardigrades in hot springs, on top of the Himalaya (6,000 m; 20,000 ft, above sea level) to the deep sea (−4,000 m; −13,000 ft) and from the polar regions to the equator, under layers of solid ice, and in ocean sediments.

On return to Earth, over two-thirds of them were successfully revived. Scientists have sequenced the entire genome of the tardigrade, AKA the water bear, for the first time.And their results suggest that this weird little creature has the most foreign genes of any animal studied so far – or to put it another way, roughly one-sixth of the tardigrade's genome was stolen from other species. Tardigrade may be little but they are the toughest form of life on Earth. When those same specimens were returned to earth and rehydrated, 68% of those shielded from the radiation survived; even a handful of those without radiation protection not only, When encountered with environmental stresses, a tardigrade will moult its skin, and inside the shed skin, it curls up into a dry, lifeless ball called a, .
