Thermoacidophile
A thermoacidophile (combination of thermophile and acidophile) is an extreme archeon which thrives in acidous, sulfur-rich, high temperature environments with low availability of organic material.
Thermoacidophiles prefer temperatures of 70 - 80 °C and pH between 2 and 3. They live mostly in hot springs like solfatares and/or within deep ocean vent communities. Classified as an archeon and an extremophile, Thermoacidophiles are found in places where most organisms would not survive.
