extremophile

(ĭk-strē′mə-fīl′)
n.
Any of various organisms that require extreme conditions of temperature, pressure, or chemical concentration, as in very cold or salty environments, in order to thrive.

extremophile

(ĕks-trēm′ŏ-fīl) [L. extremus, outermost, + Gr. philein, to love]
An organism that can thrive in exceptionally adverse environments, such as in very cold or very hot, halogenated, or salty conditions.

extremophile

a MICROORGANISM that can grow under severe or extreme environmental conditions; for example, very high temperature, high NaCl concentration, very low pH. Often they are members of the ARCHAEA.

The existence of such extremophiles on Earth strongly suggests that life may exist on other worlds--in habitats that our species would find "extreme." When we observe populations of tube worms and other species near deep sea hydrothermal vents, we are amazed by the obvious fact that they are living very well without any energy derived from the sun.
High-temperature 'extremophile' microbes, like those in the hot springs of Yellowstone National Park, US, would have survived at greater depths, down to their limit of about 4 km.
Finally, from an engineering perspective, planets are inefficient habitats: Living creatures inhabit the planet's surface (or are relatively close to it, with the possible exception of some extremophile microorganisms), making little use of the rest of the planet.
