Video by mattiasklumofficial / Gray reef sharks prowl around Neptune's Arm, off Mozambique's Vamizi island. It's a sequence from our documentary "Vamizi: Cradle of Coral." Vamizi is the largest island in the Quirimbas archipelago whose relative isolation from mainland Mozambique has preserved its natural beauty and wildlife. It has magnificent coral reefs and is a unique breeding ground for whales, dolphins, turtles, and endangered gray reef sharks.
