Eurytherm Thermoregulation Heterothermy

A stenotherm (from Greek στενός stenos "narrow" and θέρμη therme "heat") is a species or living organism only capable of living or surviving within a narrow temperature range.

The opposite is a eurytherm, an organism that can function at a wide range of different body temperatures.


Chionoecetes opilio is a stenothermic organism, and temperature affects its biology throughout its life history, from embryo to adult. Small changes in temperature (< 2 °C) can increase the duration of egg incubation for C. opilio by a full year.[1]
