Heat transfer in an Elephant

We all know the best air conditioner in the world is skin. But how much comfort does it give for some huge creatures like elephant??

Here nature's astounding science can be seen. The elephant ears are so big and the blood vessels can be seen with the naked eye. As the ears flip flap the heat in the body which is brought through blood into blood vessels, is convected to the atmosphere.Thus keeping the body at comfort temperature. The load on the skin is reduced a bit isn't it??
