Claim: Tardigrade are not mesophilic.
Evidence: They can withstand temperature ranges from 1 K -LRB- close to absolute zero -RRB- 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.
A mesophile is an organism that grows best in moderate temperature , neither too hot nor too cold , typically between 20 &.
