Goslins, for example, are able to regulate their body temperature regardless of the ambient temperature. Gecksis, on the other hand, depend on external factors for thermoregulation.
The graph below illustrates that, by showing a linear relationship between operative temperature and body temperature for gecksis.

Environment, behavior, and physiology all play a role in gecksi thermoregulation.
