Microorganisms

Did you know that some microorganisms thrive in extreme climates, from hot springs to vents located deep on the ocean floor? Organisms that live in extreme environments, meaning high temperatures or pressures, are better known as extremophiles. Some extremophiles can flourish in environments with little to no oxygen at all. Extremophiles include members of all three domains of life: bacteria, archaea, and eukarya. However, most extremophiles are microorganisms.
