The Body Temperature of the Frog

Abstract

Under most conditions the amount of metabolic heat produced by a frog is so small that the animal behaves like a non-living system and its temperature is controlled by external physical conditions.The frog’s skin is so permeable that when the animal is exposed to moderately rapidly moving air (1 m. per sec. or over) evaporation reduces its internal temperature to the wet-bulb temperature.About 25 % of the frog’s weight may be lost by evaporation before death ensues. After death water continues to evaporate at the same rapid rate until 50 % of the animal’s weight is lost.
