BIG ANIMALS AND LITTTLE CRITTERS AFRICA South Africa By MICHAEL AW The annual migration of sardines up the east coast of South Africa during the months of May to July predictably causes a frenzy amongst some of the most enigmatic animals of our oceans. Because of the cold currents along this stretch of coastline and the sardines’ appetite for plankton, the fish sometimes converge close to the shoreline and to the surface, making perfect targets for hungry predators and exciting opportunities for intrepid underwater adventurers. Imagine thousands of Cape gannets with chisel-sharp beaks plunging from the sky into a massive sardine ball; Zambezi and copper sharks charging in by the hundreds; and the engineers of the feast, common dolphins, herding the sardines towards the surface, where they can be devoured more effectively. Lurking below, unseen in the darkness of the depths, may be Bryde’s whales, 50-ton hot-blooded predators ready to come hurtling upwards to calve a giant chunk off the fish ball. Like all wildlife experiences, nothing is guaranteed. It is not uncommon to be out on the water for 10 days and come back without a single picture. But when the magic finally happens, this epitome of underwater wildlife adventures is definitely worth the wait. For the experienced diver and underwater photographer, this is the ultimate thrill ride. 17. Copper sharks get their fill of fish during Southern Africa’s famed sardine run SDOP 90
