Changing Seas
Beneath the Bridge
Season 8
Episode 804
The Blue Heron Bridge in Riviera Beach, Florida is known as one of the best shore dives in the United States. Even though at first it appears as an unlikely dive site, it is home to a rich variety of marine life, ranging from tiny nudibranchs to manta rays. Underwater photographers are documenting what lives beneath the bridge, and a scientist is studying how two species of octopus co-exist there.
