The Andros Barrier Reef, measuring 190 miles long, is the world's third-largest fringing barrier reef (the third largest living organism on the planet). It runs parallel to the eastern coast of Andros, drops about eight feet on the inland side and 6,000 feet into the Tongue of the Ocean. The variety of exotic fish species that make this place home provide a pleasurable kaleidoscope for divers and snorkelers alike. In the waters off the shores, you will find marlins, tarpons, sailfish, tunas, snappers, jacks, plus other game fish around the barrier reef. The Tongue of the Ocean is a deep ocean trench that begins about 70 feet deep and plunges to more than 6,000 feet.
