Secrets of the Whales - Season 1 Episode 2
In a classroom that spans the world's oceans, from Alaska's herring-rich coastline to Antarctica's feeding grounds, humpback calves learn their family's traditions. Cooperative hunting strategies, the longest migrations of any known mammal and communicating through complex songs to find a mate are all lessons absorbed by the younger generation.
