In a coastal resort of the Black Sea, a little girl is playing with a dolphin. This is dolphin therapy. Believers claim it can treat ailments from bedwetting to cerebral palsy. "They have a unique biological aura that helps improve the nervous system", explains scientist Ludmilla Lukina. But these dolphins share a dark secret. "No doubt about it - they were trained to attack," states retired Colonel Victor Baranets. "They can take off masks, cut cables ... there was a dolphin arms race." The Navy won't reveal if the dolphins at this resort still moonlight for them. But the money they bring in through dolphin therapy provides a welcome boost to the navy's coffers.
