Tardigrade . They have been found everywhere from mountaintops to the deep sea , mud volcanoes , and from tropical rain forests to the Antarctic . They can withstand temperature ranges from 1 K ( close to absolute zero ) to about 420 K 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 .
