Elephant walking

John Hutchinson palpated elephants' limbs to find their joints, and then he and Daniel Famini marked the joints with large dots of water-soluble, nontoxic paint. They videotaped 188 trials of 42 Asian elephants walking and running through a 100-foot course and measured their speed with photosensors and video analysis. The elephant in the video is shown walking. The average walking speed of the elephants in the experiment was 4.5 mph.
