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."
Sadly, Scar is believed to have passed away in 2012, but the friendship he had established with Armour lives on with a female whale who was his companion. She too has learned a small repertoire of actions that she performs purely for fun and of her own free will.
"She has come to fill his shoes," Armour said. "When she sees that we have come, she'll swim to the boat. She recognizes that there are people on board that she can see and interact with."
