Thermophile

Definition

A thermophile is an organism that thrives at relatively high temperatures, typically between 45 and 122 degrees Celsius (113 to 252 degrees Fahrenheit). These organisms are often found in environments such as hot springs, hydrothermal vents, and other extreme heat conditions on Earth.
