A polyextremophile (faux Ancient Greek for 'friend of many extremes') is an organism which combines several extremophilic features. For example, a polyextremophile living at the summit of a mountain in the Atacama Desert might be a radioresistant xerophile, a psychrophile, and an oligotroph. Polyextremophiles are well known for their ability to tolerate both high and low pH levels.
