Off Scotts Head, Dominica Island, a sunken garden of sponges and coral rewards a visitor, part of a growing stream of divers discovering Dominica's marine life. With one of the most vibrant underwater ecosystems in the Caribbean, Dominica offers scuba divers aquarium-clear water with visibility that can reach 100 feet (30 meters).
