Here are some bonus photographs (not in the book) that show the iridescent film created by Leptothrix discophora, one of the iron-breathing bacteria. To see the photos larger and against a black background, click on any one. You can advance to the next photograph by clicking on the image, clicking on an on-screen arrow, or pressing an arrow key on your keyboard. (The photos may take a few minutes to load with this option.)
