3. Describes organisms that can endure and function well under a broad spectrum of temperatures

Etymology: "Eurythermic" is built from two Greek-derived parts. The first, "eury-", comes from the Greek "eurys", meaning "wide" or "broad", and it appears in older scientific coinages such as "eurytopic" (wide-ranging in habitat) and "eurybiont" (an organism that tolerates varied conditions). The second, "thermal", comes from the Greek "thermos", meaning "hot" or "warm", the same root that gives "thermometer" and "thermos flask." Joined together, the parts literally describe a wide range of heat. The word is a technical coinage from the field of biology and ecology, formed in the modern scientific period rather than in classical antiquity, so no ancient Greek writer used it. Its main job is to contrast with "stenothermic", the term for organisms that tolerate only a narrow band of temperatures. A familiar example of a eurythermic creature is the common eastern oyster, which copes with the freezing winters and summer heat of estuaries.

Synonyms: thermophilic, temperature-tolerant, adaptable, resilient, flexible
