Beginning at Zavora Point in southern Mozambique, the expedition traveled 350 kilometers north along the coast to the Bazaruto Archipelago, part of a marine national park established in 1971. Along the way, they experienced a gradient of reef life, beginning with the cooler, subtropical reefs of the south—dominated by soft corals—and concluding in the tropical north, where hard corals thrive in the warm Indian Ocean. To uncover the mysteries of this important transition zone, team members made first ever dives to remote reefs and seamounts to survey their rich marine biodiversity. In places they couldn’t dive, drop cams were deployed to film the deep sea.
What they found was a bounty of flora and fauna, including corals, kelp forests, manta rays, triggerfish, honeycomb moray eels, dugongs, whitetip reef sharks, and dense schools of snappers. In Bazaruto, potato cod—a type of grouper that’s larger in size than the average team member—shared the reef with bull and leopard sharks and colorful butterfly fish. Despite the rich biodiversity they encountered, the team noted that reefs in areas such as Tofo, near Inhambane Bay, while healthy, were also suffering from the effects of fishing pressure.
