Part of speech: noun

Definitions

1. An organism capable of thriving across a broad range of environmental conditions, such as temperature, salinity, or pressure

3. An organism with the ability to tolerate extensive fluctuations in its environment and still maintain viable populations

Etymology: "Eurybiont" is a technical coinage built from two Greek elements: "eury-", from Greek "eurys" meaning "wide" or "broad," and "-biont," from Greek "bios" meaning "life." Put together, the name describes an organism that can live under a wide range of environmental conditions. The term belongs to ecology and biology, where it is set against its opposite, the "stenobiont," an organism that tolerates only a narrow range of conditions. A eurybiont might thrive in water of many temperatures or salinities, while a stenobiont is confined to one specific habitat. The pairing is a neat illustration of how scientists build precise vocabulary from classical roots: the prefix supplies the scale, and the suffix names the living thing.
