Hidden cameras show new dolphin behaviour

Film-makers have infiltrated the ocean with secret cameras to capture dolphin behaviour in the wild as it has never been seen before.

They enlisted a menagerie of creatures, such as a molluscs, sea turtle and squid, with hidden lenses to get up close and personal for a new BBC natural history programme that will be shown on the BBC on Thursday.
