Watch Marine Predator-Prey Relationships

Live-action underwater photography captures the lives of predators and prey in the world's oceans. Hunting habits and defenses are shown in sardine populations and among marlins, snake eels, scorpion fish, and several other species. The baler snail is presented as an example of a nocturnal ocean predator. The program also shows the dolphin's use of echolocation to find fish buried in the sand and the interdependence of tropical fish and sea turtles at a coral reef.
