What does it mean if an organism is an extremophile?

    Extremophiles are organisms, typically prokaryotic bacteria, that thrive in what humans would consider “extreme” environments. They include acidophiles that favor low-pH environments, alkiliphiles that like high-pH, thermophiles that grow at 40 degrees C or higher, and many more uncommon habitats. They are studied as a testament to the success of evolution and the wide ranges of biodiversity possible on the Earth.

    An extremophile is an organism that lives in extremely harsh conditions, generally considered inhospitable: examples would be deep oceanic animals under very high pressures, or organisms that live at the lips of hot water vents.

    An extremophile is an organism that lives in extreme conditions – like intense heat, intense cold, intense dryness, or immense pressure – in which other organisms could not live, such as in heat vents on the sea floor that reach extremely high temperatures. Extremophiles are generally microbes. Things that are not extremophiles are called neutrophiles.
