The greatest shoal on earth is on the move and has arrived at Kwa Zulu Natal beaches. Some experts are saying its the biggest shoal seen in a number of years.
Plenty of sharks have followed the shoal up the east coast of Africa and one reported shark attack has occurred.
Dolphins herd the sardines into bait balls that can stay together for 10 – 15 minutes at a time. Sharks, Whales and birds also come and join the feeding frenzy.
