Armour says his uncanny ability to communicate with whales in such a way began more than a decade ago with a sperm whale calf named Scar. Over years of near-daily swims with him, Armour developed a unique bond of trust and communication with the animal, which allowed him to achieve an unprecedented level of interaction.
"When I'm in the water, I make sounds which sound like their most popular combination of clicks they make when they're talking with each other," Armour said. "When I make these sounds, they stop to listen and then I can interact more closely with them. I've now been able to show them some maneuvers in the water, like spinning."
