Icy Killers: Secrets of Alaska's Salmon Shark

In Alaska's freezing waters lurk some of the ocean's most agile killers - salmon sharks. They are a close relative of the great white shark and one of the few sharks with warm-blooded capabilities. Every year, thousands make the journey for a feeding frenzy in Prince William Sound, a rugged wonderland where enormous glaciers carve and reshape the land. Despite its severe and unforgiving landscape, this area is a rich ecosystem, home to huge schools of Pacific salmon and salmon sharks.
