A curious sperm whale and her calf attempted to introduce themselves to a submersible robotic spy whale that was created by John Downer Productions for the BBC/PBS series Spy in the Ocean narrated by David Tennant. Being that the spy was the size of a young calf, the welcoming mother used clicking sounds to greet the stranger and then let the calf do the same. This particular action shows trust amongst sperm whales.
In a magical close encounter, Spy Whale is greeted by an inquisitive female who, in astonishing scenes, attempts to communicate. In a touching sign of acceptance, she even introduces her calf to Spy Whale.
