Some types of extremophiles

Endoliths Live in microscopic spaces within rocks 

Cryptoendoliths Live in fissures, faults in deep subsurface 

Hypoliths Live underneath rocks in cold deserts 

Litoautotrophs Source of carbon is CO2, derive energy from mineral compounds 

Metallotolerants Capable of tolerating high levels of metals like copper, cadmium, zinc
