Like commuters in a busy train station, squirrelfish, yellow goatfish, and blue-striped snapper jostle one another in a dark tunnel 80 feet beneath this surface hazard. The photographer Georgienne Bradley saw her first whale shark here. "Instead of being frightened by the divers, he seemed intrigued," she wrote in Skin Diver magazine (9/94).
