Dr. Keith Ricks: [narrating] For the creatures that live there, and even for the creatures that occasionally visit, the ocean can be a terrifying place. What fills one animal's belly ends another animal's life. But if you ever want to watch real horror in action, follow a shark finner around for a day. Watch him hook a live shark, lift it out of the water and slice its fin off - then drop it back to die... all for a bowl of shark fin soup. Fortunately, shark finning is illegal in Florida waters... unfortunately nobody cares.
