• Resumen

  • For big animals, staying cool is a challenge--and yet elephants, the largest land animals in the world, live in some of the hottest places. Large, warm-blooded animals not only generate a lot of internal heat, they have a smaller surface area relative to their volume. To maintain their body temperature when it's hot, then, an elephant has to lose far more heat per unit of surface area than a person. The bigger the elephant, the bigger the problem. What's more, elephants don't sweat. They don't pant either, probably because it doesn't work well for such a huge animal. Here, Hamzelou talks about elephants have some amazing tricks to keep cool.
