Shark Feeding Frenzy in South Africa A diver is circled by a shark feeding frenzy off the coast of Port Elizabeth, South Africa. This is the breathtaking moment a daredevil diver is swept up in a whirlwind feeding frenzy of sharks. A school of 16ft, 900kg tiger sharks and oceanic black tips swarm the vulnerable swimmer who appears to remain surprisingly calm. The unnamed diver fearlessly lowered a bucket packed with sardines - a favorite of the sharks - into the water, all while still clinging to the line. He was quickly surrounded by dozens of the creatures. Picture: Rainer Schimpf/Barcroft Media
