Tardigrade/Water Bear Species: Acutuncus antarcticus

There are approximately 1,300 known species under the phylum Tardigrada. They are found almost anywhere, including mountaintops, tropical rainforests, the deep sea, and the Antarctic. They are extremophiles, capable of surviving a few minutes at both 151°C (304°F) and −272°C (−458°F; 1 K) and a few days at −200°C (−328°F; 73 K).

This particular Antarctic species has been found to be able to survive for 30 years at −20°C (−4°F). (Tsujimoto et al. 2016 Cryobiology)
