A human can only survive three weeks without food and eight to ten days without water, while Tardigrades can survive thirty years without food or water. These organisms are found almost anywhere on earth. Tardigrades can survive in wild and extreme temperatures such as on mountain tops and the deep sea. As long as the temperature doesn't reach lower than -328 F or higher than 304 F these little guys can survive, they can even endure having their bodies frozen and thawed. The way these magnificent creatures can do this is by a process known as cryptobiosis which is a defined state in which metabolic activities come to a standstill; it is almost like a deathlike state. The most common type of cryptobiosis in the over 900 species of tardigrades
