1. Halophiles are archaea that live in extremely salty areas.
2. Acidophiles are archaea that live in extremely acidic places.
3. Thermophiles are archaea that live in extremely hot areas.
4. Methanogens are archaea that are found in areas with methane.
5. Psychrophiles are archaea that live in extremely cold places.
6. Alkaliphiles are archaea that thrive in alkaline environments with a pH of 9 to 11.
