Poikilothermic organisms, also known as ectotherms, are those whose body temperature varies with the environment, such as reptiles, amphibians, and fish. In contrast, endothermic organisms, or warm-blooded animals, maintain a constant internal body temperature regardless of external conditions, which includes birds and mammals. Therefore, poikilothermic and endothermic organisms belong to different physiological categories and do not overlap.
