Dolphins called and Peter Sugarman answered. We Yu: Dolphins Calling traces his fifty-year quest to break through the acoustic barrier separating our two species. Drawing on Navy sonar training, cognitive behavioral science, and a universal language called aUI, Peter pursued one luminous idea: humans and dolphins can genuinely speak with one another. He pitched into pools with bottlenose dolphins Joe and Rosie, engaged with spotted dolphin pods, and helped build the AI-powered translation tools now turning that dream into reality. Part science, part spiritual reckoning, this account delivers an urgent message-the dolphins are calling. It's time we listened.
