Quizplus · Accepted Answer

Poikilothermic organisms allow their body temperature to vary with the ambient temperature, unlike strict homeotherms that maintain a constant body temperature. Elephants, by allowing their body temperature to vary during the hottest parts of the day, exhibit a poikilothermic characteristic, even though they are generally considered homeotherms.
