Examples

  • Another extremophile, Deinococcus (formerly Micrococcus) radiodurans exhibits extraordinary resistance to ionizing and ultraviolet radiation and desiccation, as well as many other agents that damage DNA.

  • Another group of extremophiles, the halophiles, grow in highly saline environments like natural salt lakes and solar salt-evaporation ponds.

  • Could these be the same extreme extremophiles that were on early Earth?

  • The question is, are extremophiles really organisms that live on the edge and love it?

  • And this extremophile is known as acetic acid bacteria.

  • Do we have reason to believe that there were extremophiles already early in Earth's history?

  • Most of these extremophiles have been discovered in the past fifteen years, and it is likely that the number of discoveries will rapidly expand as research into extreme environments continues.

  • This biological window is largely based on studies of "extremophiles"—bacteria that have adapted to extreme environments.

  • One thing that has become apparent in the study of extremophile bacteria is that once "life" gets a foothold, it is extremely difficult to eliminate it (witness several iceball Earth eras).

Morphology

extremophile = extreme (semi-transparent) = extreme + phile

The scientific sense is built from 'extreme' + '-phile' ('loving'), but the exact reference to organisms in harsh environments is a specialized technical term.

Etymology

Extremophile combines extreme 'very harsh or far from the usual' and phile 'lover', the same -phile you see in bibliophile (a book lover). So an extremophile is an organism that 'loves' and can live in very harsh places like boiling springs or deep ice.
