Rhinos don’t have sweat glands, which is just too bad for Us. However, We are accomplished at panting and gasping. The point of all those activities is to regulate body heat, especially with sweltering weather.
Many Rhino stomping grounds offer little shade, so we get mud or dust onto our skin to deflect the sun’s rays. Or We go into whatever water is around. That takes practice. Also, it requires no crocodiles.
Life in the Wild demands planning and lot of luck.
