Do warm blooded animals emit radiation?
Everything, alive or not, emits infra-red radiation, the warmer they are, the more they emit
The difference is that cold-blooded animals cannot control their temperature. Warm-blooded animals maintain a constant temperature no matter what the temperature around them is. For example a fish is cold-blooded and we humans are warm-blooded. We are mammals, all mammals are warm-blooded. Reptiles are cold-blooded. In other words, warm blooded animals have a constant body temperature while cold blooded animals do not.
cold-blooded animals must live in warm climates; warm-blooded animals can more or less live anywhere. reason: Warm-blooded animals produce their own body heat, so as to always keep their enzymes at the optimal temperature. Cold-blooded animals cannot do this. As the temperature falls, cold-blooded animals become disabled. They cannot move their muscles, or digest their food, or transport oxygen to their tissues.
