In Narwhals — Unicorns of the North, narrator Sir David Attenborough describes how a group of narwhals heads into the bay to find food when it runs into another group of narwhals traveling in the other direction. After a stand-off, they all swim back into the bay. Then learn about the mystery of the narwhal’s tusk. This video is excerpted from BBC’s Frozen Planet, a series that shows a fragile world of beauty and hostility, where nature finds a way to survive and thrive in frigid conditions.
