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). Sitting 1-1½ miles off the eastern coast, it runs parallel to the island. Its depth ranges from about eight feet on the inland side to 6,000 feet into the Tongue of the Ocean, a deep ocean trench that begins about 70 feet deep. The reef's underwater forest is home to a wide variety of exotic marine life, including over 160 species of fish and coral, which provide a pleasurable kaleidoscope for divers and snorkelers alike. It is said to be the only place in the world where there is more than one Nassau grouper aggregation. You will also find marlins, tarpons, sailfish, tunas, snappers, and jacks in the waters offshore, plus other game fish around the barrier reef.
