All lions are extremely sensitive to heat, and many lion behaviours seek to minimize heat stress. Sleeping in the day and limiting most activity to the night is one example; others include lying on their backs to expose their thin-skinned b
ellies, resting on high rocks to catch the breeze, and panting after exertion or large meals. Unlike dogs, lions do not have cool, wet noses, and unlike people, they don’t sweat. Their only means of thermoregulation are breathing (panting) and radiating heat from the skin. Body Temperature: 38.05 – 39.16°C / 100.5 – 102.5°F
