Barney's Barrier Reef is a British documentary program launched by the CBBC in 2009, presented by Barney Harwood and Gemma Hunt. The structure of the program shows the links between animals from the Great Barrier Reef. It involves at least 10 to 12 animals each episode. Barney's Barrier Reef mostly involves fish since the Great Barrier Reef is in an ocean. Land animals are hardly used in this series. Barney's Barrier Reef featured 20 episodes.
