WebbAmong amphibians, behavioral thermoregulation is difficult to separate from behavioral mechanisms for water conservation because they lose water readily through the skin. . For reptiles, the most apparent process affected by temperature is behavior; a cold reptile is not as active as a warm one. Webb20 nov. 2024 · Revisions: 31. Cutaneous circulation is involved in the supplying blood to the skin. The skin is not very metabolically active and thus has relatively small energy requirements.
