they always there , there is a resident white between fish hoek and millers same tagged fish patrols the same area each year. more whites are being seen because more people are making the effort to look out for them . a few years ago the helicopter trips from the waterfront and airport round the peninsula started at muizenberg to cape piont, then over sea piont back to the water front now they fly from strand to the piont for the very reason people want to see sharks .like with all wild animals common sense needs to be used , you dont climb out of your car in the kruger to go swim in the water hole.If the flags are out sirens go off, people are on the beach taking photos of the shark dont go swim right then.
