Extremophiles Live Where Most Things Can't
Extremophiles thrive in environments that humans deem "extreme," from lakes with high salt concentrations to deep-sea vents. They produce enzymes called "extremozymes" that help them to survive in these conditions. Specialized groups of extremophiles have different names; an acidophile, for example, is an organism that experiences optimal growth in an acidic pH, whereas a hypolith is an organism that lives beneath rocks in cold deserts.
