Strain 121 ("Geogemma barossii") is a single-celled microbe of the domain Archaea. First discovered 320 km (200 mi) off Puget Sound near a hydrothermal vent, it is a hyperthermophile, able to reproduce at 121 °C (250 °F), hence its name. It was (at the time of its discovery) the only known form of life that could tolerate such high temperatures.
