    In this state, they can go without food or water for several years. [3] Further, in that state they become highly resistant to environmental stresses , including temperatures from as low as −272 °C (−458 °F) to as much as +149 °C (300 °F) (at least for short periods of time [ 12 ] ), lack of oxygen , [ 3 ] vacuum , [ 3 ] ionising ...

    Tardigrades can withstand 1,000 times more radiation than other animals, [17] median lethal doses of 5,000 Gy (of gamma rays) and 6,200 Gy (of heavy ions) in hydrated animals (5 to 10 Gy could be fatal to a human). [18] Earlier experiments attributed this to their lowered water content, providing fewer reactants for ionizing radiation. [18]

    Anhydrobiosis in the tardigrade Richtersius coronifer. Anhydrobiosis is the most studied form of cryptobiosis and occurs in situations of extreme desiccation.The term anhydrobiosis derives from the Greek for "life without water" and is most commonly used for the desiccation tolerance observed in certain invertebrate animals such as bdelloid rotifers, tardigrades, brine shrimp, nematodes, and ...

    Tardigrades are also able to survive temperatures of close to absolute zero (−273 °C or −459 °F), [5] temperatures as high as 151 °C (304 °F), radiation that would kill other animals, [6] and almost a decade without water. [7] Since 2007, tardigrades have also returned alive from studies in which they have been exposed to the vacuum of ...

  9. Tardigrades in space - Wikipedia

    en.wikipedia.org/wiki/Tardigrades_in_space

    Tardigrades are small arthropods able to tolerate extreme environments. Many live in tufts of moss, such as on rooftops, where they get repeatedly dried out and rewetted. Others live in the Arctic or atop mountains, where they are exposed to cold. When dried, they go into a cryptobiotic 'tun' state in which metabolism is suspended.
