Describe the attack on Bruder.

Bruder swam with great speed, past the safety ropes and soon almost out of sight. Bruder's movement through the water caught the attention of the great white, which was on patrol. Perhaps the light flickering off the palms of Bruder's hands and bottoms of his feet looked like fast-moving fish to the hungry predator; or, the shape and color of the swimmer may have resembled a seal. The shark attacked from behind with a fury. Someone on shore thought they saw a red canoe tip over. When the rescuers reached the spot where Bruder was attacked, they realized that the "red" the people saw was a large circle of blood. The shark had attacked repeatedly, but the men were able to pull Bruder into the boat. Both his feet were gone. The men couldn't stop the bleeding and rowed ashore as fast as they could. Charles Bruder lost consciousness on the way back to the shore.
