How do some bacteria manage to survive the most severe environmental conditions temperature as well as salinity?

These special and very old bacteria are called Archaea bacteria. They are associated with extreme environments, contain unique cell walls and have unique internal structures.

Archaea bacteria that are found in hot springs are called thermophiles and those found in high salt content areas are called halophiles.
