Dolphins leap for joy through the waves, as we begin our journey into the blue. Our first stop is the coral reefs, where we meet fascinating characters like the ingenious tusk fish that uses a tool to open its food. In the great forests of the sea, we find a cunning octopus who shields herself in an armoury of shells to hide from predators.
