Portrait of a Marine Iguana with a Salty Wig

Marine Iguanas are vegetarians and have a hard jaw for scraping algae from rocks under water. They have salt glands between their eyes and nostrils that concentrate and remove salt. They sometimes sneeze the salt out to warn off over-inquisitive tourists and intruders. The spray often shoots up into the air and falls back on their head, forming a white "wig". Puerto Egas, Santiago Island.
