This photo captures the appearance of a marine iguana, a species found only in the Galapagos Islands. The iguana is perched on a black volcanic rock, surrounded by the deep blue sea. The mottled brown and black skin of the iguana suggests that it is molting, a process where old skin is shed to make way for new growth. The photo was taken with a NikonD90 camera and Nikkor 18-105mm lens.
