A small marine iguana absorbs heat from the sun on Mosquera Islet in the Galapagos archipelago. These amazing reptiles can vary their body size (including bone length) to survive El Nino seasons when food is scarce. The iguanas in this area were hit pretty hard by the recent El Nino, and so they are pretty small. This one was only 2-3 feet long and has a very short tail in comparison to it's body size. This photo was taken as El Nino ends.
