Photo by Thomas Peschak @thomaspeschak | Sharks rarely hunt birds. To my knowledge, the only repeat offenders are tiger sharks. Yes, great whites and other species will snack on the occasional gannet or petrel, but this is not the norm. In this scene—a tidal flat on a tropical atoll—the egret has little to fear from the blacktip reef shark. They both specialize in eating small fish that ride the currents in and out of the lagoon.
