"Marine iguanas, endemic to the Galapagos, are one of the most iconic species in the archipelago," says de Frias. "They are like miniature dragons, especially in low angle eye-to-eye portraits like this one. This individual was resting on the black rocks of Santa Cruz Island, sunbathing after a foraging dive. By sheer luck, I photographed the split-second in which it was sneezing the excess salt it had absorbed during its dive. Sneezing is not a discomfort signal, it is perfectly natural behaviour. I made sure not to disturb the animal, shooting from a very safe distance, using a 600mm lens."
