Watch Fur Seals: The Dark Side

All through the seal's coming of age, the self-taught animal moves through different stages that will in turn enable him to produce offspring: after a birth on land, the seal leaves for the high seas, endures storms, and above all, learns. He learns to hunt, to fight, to become an opportunistic predator but also to share the dusky dolphins' experience or to escape the killer whale's jaws.

Fur Seals: The Dark Side is a 2007 documentary with a runtime of 51 hours.
