Glimpse into dolphins' schooling

Extraordinary scenes of the early days of a newborn dolphin's life have been caught on camera for the first time – including an apparent fishing lesson and a gathering of females to see the proud mother and baby.

The footage in a BBC2 documentary, to be aired on Wednesday, also shows a young female's attempt to kidnap the baby, various hunting techniques employed by the mammals and a shark attack.

The makers of The Dolphins of Shark Bay used miniature cameras to capture the first hours of a calf's life and previously unseen sights that point to the animals' intelligence and complex relationships. The film follows

Puck and her eighth calf Samu, both shown above, two of the bottlenose dolphins studied off western Australia.

The Dolphins of Shark Bay will be shown at 8pm on Wednesday on BBC2 .
