South Africa's annual Sardine Run has been dubbed 'The Greatest Shoal
on Earth'. This piscine spectacle occurs annually when millions of
southern African pilchards follow a cold current northwards along the
coast. An array of predators, including dolphins, sharks and gannets,
take advantage of the abundant food supply and show up in their droves
to feast on the silvery shoals.
Dolphins will typically split the
shoals into smaller tightly packed clusters (known as baitballs) before
the other predators move in to feed. Filming under these conditions can
be very challenging, and camera operators are often bumped or knocked as
they try to capture that perfect shot in the thick of the fast-moving
action. www.earth-touch.com
