+**Cold Blooded** describes organisms whose body temperature is primarily regulated by external sources rather than internal physiological processes. These creatures, often termed [Ectotherm](/wiki/ectotherm)s, see their internal temperature fluctuate with environmental conditions, a state also known as [Poikilotherm](/wiki/poikilotherm)y. This adaptation influences their behavior and metabolic rate.
