Tardigrades can live in high temperatures.
Mud volcano . The mud produced by mud volcanoes is most typically formed as hot water , which has been heated deep below the earth 's surface , begins to mix and blend with subterranean mineral deposits , thus creating the mud slurry exudate . Mud volcano temperatures can range from near 100 C to occasionally 2 C , some being used as popular `` mud baths . '' 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 .
