Sperm Whales: Back From the Abyss

Wildlife film about sperm whales, revealing the secret lives led by these often misunderstood ocean giants. Scientists all over the world are now learning about the secret lives of sperm whales, the world's largest hunters that spawned the legendy of Moby Dick. Although Mellville painted them as fearsome beasts of the sea, they are actually shy creatures, and cameraman Rick Rosenthal needed patience and persistence to film them at close quarters. They turn out to be efficient hunters with a close family network involving sophisticated and vocal social lives.
