VIDEO: New Clip Of Dolphins: Spy In The Pod Narrated By David Tennant

John Downer Productions have released a new video clip from the first episode of Dolphins: Spy in The Pod which airs on BBC One this week. The clip shows some of the unique, never-before-filmed behaviour of wild dolphins captured by one of the production company's innovative spy-cams.

In Costa Rica, Spy Tuna infiltrates a huge megapod of spinner dolphins and captures some arresting images.
On occasions, superpods of spinner dolphins come together to form one of the greatest wildlife spectacles on earth...a megapod of over 3000 dolphins. Here, one such moment is filmed.

The first of the two-part series Dolphins: Spy In The Pod can be seen on BBC One on Thursday 2nd January at 8pm GMT. The programme is narrated by David Tennant with music by Will Gregory and the series is directed by John Downer.
