This photo was taken while the photographer was recently visiting the Wilhelma Zoo in Stuttgart, Germany. He was attempting to photograph a monkey eating from a feeder when the fence next to him shook. When he looked, there was another monkey right next to him grabbing on. The photographer whipped his camera around with almost no time to refocus to take this photo, just before the monkey scrambled away.
