Sharks and Grunts, French Polynesia, 1997

Photograph by David Doubilet

In the fertile waters of French Polynesia's Tuamotu Archipelago, a school of blue-striped grunts beats a fast retreat as a pair of blacktip reef sharks lurk in the distance. Although the nutrient-poor soil of the French territory limits its terrestrial flora and fauna, the archipelago's waters are among the world's most scenic, species-rich spots.
