A sardine feeding frenzy has been captured on camera in
remarkable detail. A BBC crew filmed thousands of sharks,
dolphins and seabirds feasting on shoals. Each winter, cool
ocean currents drive millions of the small fish northwards along
the eastern coast of South Africa. These immense shoals,
squeezed into this narrow cold-water corridor, provide an
incredible feeding opportunity for the array of predators that
live in and around these waters. The sardine run forms part of
the BBC Natural History Unit series: Nature's Great Events.
Nature's Great Events: The Great Tide is on Wednesday 4 March on
BBC One at 2100 GMT and is repeated on Sunday at 1800 GMT
