Until the 1970s this group of microbes was classified as bacteria.

21. EXTREMOPHILES

22. Sulfolobus is an extremophile that is found in hot springs and thrives in acidic and sulphur-rich environments.

24. Methanosarcina rumen is anaerobic, and is found in places with little or no oxygen. It is a methane- producing organism that digests decaying organic matter. It is found in the rumen of a group of animals called ruminants such as cattle and sheep.

26. Staphylothermus marinus is an extremophile found in deep ocean hydrothermal vents, thriving on volcanic sulphur and surviving in water temperatures of up to 98°C.

28. Halococcus salifodinae is found in water with high concentrations of salt. These high salt concentrations would be deadly to most other forms of life, and so H. salifodinae is also known as an extremophile.

29. Colorful "salt-loving" Archaea thrive in these ponds near San Francisco.
Used for commercial salt production, the ponds contain water that is five to six times as salty as seawater.

30. Methanococcoides burtonii is an extremophile and was discovered in 1992 in Ace Lake, Antarctica, and can survive in temperatures as low as -2.5 °C.
