Darwin Island, Gal??pagos Islands, Ecuador
1999
David Doubilet

“Pacific swells push against Darwin Island, where white salema and black triggerfish feed beneath breaking waves. Here 20 years ago Jerry and I were intimidated by huge squadrons of sharks???hammerhead and the more aggressive Gal??pagos sharks. Now I see just one hammerhead nearby. The sharks too have been driven into deeper waters in search of prey, and when I'm down to 150 feet [46 meters] I see hundreds of them far beneath my fins, disappearing into a twilight sea.”
