Made up of underwater structures rarely visited by man including shipwrecks, massive coral reefs and bottomless sinkholes, it's the backdrop for one of the most dangerous careers in the world: commercial spear fishing. Spearfishers risk their lives scuba diving to extreme depths in order to hunt down and pierce some of the ocean's most sought after, and expensive fish. Currently 0/10
