Location on Google Maps Wikipedia Reference sharks are another important part of South African baitball team ! ^_^ There are a few species present on bait balls - but most representative one - oceanic blacktips, most common sharky sight on the Wild Coast.
Movement and shape of a bait ball is designed by nature to confuse sharks, this is why they spend most of time there in seemingly disoriented state. It takes a lot of passes through it for shark to finally sense individual fish and start feeding - when this happens something clicks in it's head and it switches into very aggressive and dangerous frenzy state. But even before this happens movement of shark and bait ball reacting to it produces beautiful sights of natural geometry.
