| This little extremophile is known as a Tardigrade or “water bear”. These critters can be found all over the world--from the high Himalayas (above 6,000 metres (20,000 ft)), to the deep sea (below 4,000 metres (13,000 ft)) and from the polar regions to the equator. One of the reason’s they can do this is because they are virtually indestructible; In 2008, water bears were the first animals demonstrated to be able to survive the vacuum of space (for over 10 days!). Furthermore, they have also survived very high pressures, up to 6,000 times that of the regular atmosphere (nearly six times the pressure of water in the deepest ocean trench, the Mariana trench). They can survive being blasted with intense radiation (humans die after being exposed to about 500 "roentgens" of radiation, the water bear, however, can survive 570,000)… as well as being exposed to temperatures near absolute 0 (−459 °F), and as high as +303 degrees Fahrenheit. It can also lose ~99% of the water in its body… Once, after adding water to a water bear that had been dead for 120 Years, it came back to life.......
