Polyextremophile
An extremophile (from Latin extremus meaning "extreme" and Greek philiā (φιλία) meaning "love") is an organism that thrives in physically or geochemically extreme conditions that are detrimental to most life on Earth. In contrast, organisms that live in more moderate environments may be termed mesophiles or neutrophiles.
In the 1980s and 1990s, biologists found that microbial life has an amazing flexibility for surviving in extreme environments — niches that are extraordinarily hot, or acidic, for example — that would be completely inhospitable to complex organisms. Some scientists even concluded that life may have begun on Earth in hydrothermal vents far under the ocean's surface. According to astrophysicist Dr. Steinn Sigurdsson, "There are viable bacterial spores that have been found that are 40 million years old on Earth — and we know they're very hardened to radiation." On 6 February 2013, scientists reported that bacteria were found living in the cold and dark in a lake buried a half-mile deep under the ice in Antarctica. On 17 March 2013, researchers reported data that suggested microbial life forms thrive in the Mariana Trench, the deepest spot on the Earth. Other researchers reported related studies that microbes thrive inside rocks up to 1900 feet below the sea floor under 8500 feet of ocean off the coast of the northwestern United States. According to one of the researchers,"You can find microbes everywhere — they're extremely adaptable to conditions, and survive wherever they are."
Most known extremophiles are microbes. The domain Archaea contains renowned examples, but extremophiles are present in numerous and diverse genetic lineages of bacteria and archaeans. Furthermore, it is erroneous to use the term extremophile to encompass all archaeans, as some are mesophilic. Neither are all extremophiles unicellular; protostome animals found in similar environments include the Pompeii worm, the psychrophilic Grylloblattidae (insects), Antarctic krill (a crustacean) and Tardigrades (water bears).

Ryan Hooton introduces us to one of the most remarkable heroes of survival in the natural world: a bacterium that could potentially live on Mars. When asked to think of heroes of survival, we often call to mind the names of Douglas Mawson and Ernest Shackleton: enduring the frozen desolation of Antarctica, and (barely) surviving.

Search, Isolation and Characterization of Radiation Resistant Bioprospects from Extreme Environments in Puerto Rico | Rosasantana's Blog
Abstract Since the discovery in 1956 of the bacterium Deinococcus radiodurans, this Polyextremophile has been studied due to its ability to survive in extreme environments, and has served as a model in the study of other radiation resistant microorganisms. These studies could be key to develop new biotechnological strategies, such as bioremediation of extremely contaminated and highly toxic environments, and new therapeutic techniques for cancer and other serious illnesses.
