-Tardigrade-
Otherwise know as the &lsquo;water bear.&rsquo;
Tardigrades are able to survive in extreme environments that would  kill  almost any other animal. Some can survive temperatures of &minus;273&nbsp;&deg;C   (&minus;459&nbsp;&deg;F), close to absolute zero, temperatures as high as 151&nbsp;&deg;C (304&nbsp;&deg;F), 1,000 times more radiation than other animals,  and almost a decade without water. In September 2007, tardigrades were  taken into low Earth orbit and for 10 days were exposed to the vacuum of  space. After they  were returned to Earth, it was discovered that many  of them survived  and laid eggs that hatched normally. Recent research  has revealed that they can also withstand pressure of  6,000  atmospheres, which is nearly six times the pressure of water in  the  deepest ocean trench.
