Marine Iguana, La Fe Island, Galapagos Islands, EcuadorMarine iguanas are the only lizards on earth that swim in the ocean. They are herbivores and as you can see from the lava-rock landscape they inhabit in the Galapagos Islands, there isn’t much foliage to feed on. They’ve adapted to a life in the water where there is a far greater abundance of plant life. I was really hoping for an underwater shot while snorkeling, but they move much more quickly in water than out. No problem getting all sorts of shots as they rested for the good part of the day on the black rock of La Fe Island. Nikon D800 with Nikkor 17-35mm lens (at 17mm) ISO 400, f/10 at 1/800th of a second.
