The Blue Heron Bridge in Riviera Beach, Florida, is known as one of the best shore dives in the United States. What appears as an unlikely dive site at first is home to a rich variety of marine life, ranging from sea horses to manta rays. A scientist from Florida Atlantic University is studying the two species of octopus that live here, to better understand how these animals can co-exist in one area without competing with each other. In addition, a group of dedicated underwater photographers is contributing to scientific knowledge by documenting the large number of nudibranchs, or sea slugs, that live beneath the bridge.
