Pyrolobus fumarii, (literally the "firelobe of the chimney"), is a species of archaea known for its ability to live at extremely high temperatures that kill most organisms.[1][2]

It was first discovered in 1997 in a black smoker hydrothermal vent at the Mid-Atlantic Ridge, setting the upper temperature threshold for known life to exist at 113 °C, but more recently Methanopyrus kandleri has been discovered which can survive temperatures up to 122 °C.  [3][4] The species "freezes" or soldifies and ceases growth at temperatures of 90°C and below.[5]

Strain 121, a microbe from the same family found at a vent in the Pacific Ocean, survived and multiplied during a 10-hour interval spent at 121 °C in an autoclave.[3]
