This is the largest living lizard in the world, a Komodo dragon. They are native to three islands in Indonesia. The bacteria in their mouth are so lethal that when they bite prey animals, such as deer, they follow them for several days until they die from the infection. Once bitten, death is certain. I was able to photograph the dragons from ground level, and I think that made a huge difference in the visual impact of the picture. These are dangerous predators, and my photo tour group and I were constantly warned by the national park rangers to keep our distance. I used a 100-400mm Canon zoom specifically to keep at least 30 feet between the dragons and myself. To capture the flickering tongue, I used a frame rate of 14 fps. My settings were 1/250, f/14, and 2500 ISO.
