Hyperthermophiles are a type of extremophile microorganism that thrive in extremely high temperatures, typically above 80°C (176°F). They are primarily found in environments such as hydrothermal vents, hot springs, and other geothermal areas. These organisms are often archaea and exhibit unique adaptations that allow their cellular structures and enzymes to function optimally under such extreme conditions. Their study is significant for understanding life's limits and has potential biotechnological applications, such as in industrial processes that require high-temperature stability.
