Whales' watery world of muted light and color is dominated by sound. Whales are masterful singers, capable of sending their calls over thousands of miles. To whales, these vocalizations are not only a means of communication, but also one of literal survival throughout their long migrations. Follow blue, humpback, orca, right whales and dolphins in their annual journeys to discover how the underwater dimension of sound influences and guides their feeding, breeding, navigation, and socialization.
