I figured an animated gif might be the best way to illustrate the changing colors of a short horned chameleon (also known as an elephant eared chameleon). The first shot, when the chameleon was a nice colorful blue and green, was how I first encountered the animal on a night hike in Madagascar’s Ranomafana National Park. The next two shots show how the color of the skin quickly turned to brown as the chameleon reacted to my presence and flash. This change happened almost immediately as the shots were all taken within thirty seconds.
