Marine Iguanas are often found in large numbers clinging to the rocks and lava along Galapagos shorelines.They are the world's only sea-going lizards. There are seven kinds of them, spread around the various islands. The most colorful are found here on Espanola. In this image, I move in on a single hand, resting comfortably on the back of a red Marine Iguana at Punta Saurez. Since these iguanas gather close to each other in huge colonies, such gestures are common. Whether it is a touch of affection or simply a convenient resting posture remains a mystery. I leave such answers to the imagination of the viewer.
