Trapped between the shore on one side and the warm water on the other, sardines swim straight towards the enermy. They fall back to their instinctive defence mechanism and shoal together in a huge mass to confuse their predators. But the dolphins have a strategy which turns this ball of fish to their advantage. Working together they separate off a pocket of sardines.
