A marine iguana lazes around on Puerto Egas on Santiago Island, soaking up the sun to warm up after they cooled down at night, and before they would dive into the water to feed. A gland connected to the nostrils removes salt from the body, which is then expelled by "sneezing". The spray often shoots up into the air and then falls back on the head, where it forms the white "wig" often seen on marine iguanas.
