Todd Endris thinks so. He was sitting on sis surfboard off a beach in California waiting for a good wave to ride. Suddenly,a great white shark attacked him. Endris held onto the board,but the shark attacked him a second time. The shark took hold of Endris's leg and they swam in circles between Endris and the shark. Endris was able to get back on his surfborad and reach the shore. An ambulance almostdied. Endris believes the dolphins saved his life.
