If it weren't for the eye you might think this was an aerial view of a dried-up river bed. But, when you realize it isn't, the deep crags of the elephant's skin become the center of our attention. The African elephant is the largest of all land mammals, and during my trip to Tanzania my tour group was treated to many sightings of these magnificent animals. This one was eating acacia leaves when I zoomed in my lens to capture the wrinkles and the dried mud on his skin. Wrinkles, as we learned, act as a cooling mechanism by increasing the skin's surface area which traps moisture and allows for a longer evaporation time, thus keeping elephants cooler longer.
