Stenothermic refers to an organism's ability to exist only within a narrow range of temperature. Some synonyms that can be used for the term stenothermic would include temperature-sensitive, temperature-dependent, thermally constrained, and thermo-restricted. These words all evoke the same meaning as stenothermic, which is an organism that is only capable of existing in a certain temperature range. Other synonyms that could be used include heat-intolerant, cold-intolerant, and limited-temperature. These terms highlight the limited range in which stenothermic organisms can survive and thrive and help to further elaborate on the concept of temperature sensitivity.
