Swimming alongside some of the most captivating and clever animals on the planet, these new spies are always on the move – catching the waves with surfing bottlenose dolphins and speeding with a megapod of spinner dolphins.　　From the team at John Downer Productions that brought you the unforgettable Penguins – Spy In The Huddle, this is one of the nation’s favourite animals seen as never before.　　John Downer says: “Unlike Penguin-cams, this time our spy creatures had to keep pace with fast-moving dolphins, often out in the deep ocean.
