Tardigrades are one of the most resilient animals known. Individual species of tardigrades can survive extreme conditions that would be rapidly fatal to nearly all other known life forms, including complete global mass extinction events due to astrophysical events, such as supernovae, gamma-ray bursts, or large meteorite impacts. Some tardigrades can withstand extremely cold temperatures down to 1 K (−458 °F; −272 °C) (close to absolute zero), while others can withstand extremely hot temperatures up to 420 K (300 °F; 150 °C) for several minutes, pressures about six times greater than those found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a human, and the vacuum of outer space. #urbanphotography #maine #UMF #photography #tardigrades #extremeanimals (at Farmington, Maine)
