The closer we come to a Land Iguana, the more learn about its bizarre appearance. I zoomed in on the face of one of them, and caught it licking its foot. The small pink tongue becomes the focal point of the image, contrasting in both color and texture to the scaly skin that covers the body. There are 15,000 of these creatures in the Galapagos. They live in burrows, and eat cactus pads and insects. They can grow as large as three feet long. The sight of a huge Land Iguana licking its foot is incongruous -- at a glance, it seems vulnerable as a puppy, yet its giant claws are as menacing as a dinosaur's.
