Nature: The Mystery of Eels

Naturalist James Prosek examines the freshwater eel, sharing what's known about its behavior while detailing how it's become the center of a multibillion dollar business--Japan alone consumes 130,000 tons of eel a year. In Maine, baby eels are caught in the early spring as they make their way upstream from the sea; they're then shipped to China, where they're raised to maturity and distributed to the rest of the world.
