An article like this that makes no mention of Tardigrades?

"They are among the most resilient animals known, with individual species able to survive severe conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other forms of life. They have survived exposure to outer space." [1]
