... Homeotherms are endothermic animals that maintain a very consistent body temperature within a very narrow temperature range. Birds and mammals are usually very strict homeotherms. Homeotherms can function quite efficiently in both hot and cold environments. Poikilotherms are animals that have not developed mechanisms for regulating the temperature of their internal environment. Therefore, their internal temperature changes with the temperature changes ... should be avoided at all costs. (4) Cold tolerance or supercooling occurs nin many poikilotherms when body temperature is brought down ...
