     Eight-year-old Jesse Arbogast was playing in the sea late one evening in July 2001 when a 7-foot bull

shark attacked him and tore off his arm. Jesse's uncle jumped into the sea and dragged the boy to shore.

The boy was not breathing. His aunt gave him mouth-to-mouth resuscitation (人工呼吸) while his uncle

rang the emergency services. Pretty soon, a helicopter arrived and flew the boy to hospital. It was a much

quicker journey than the journey by road.

     Jesse's uncle, Vance Folsenzier, ran back into the sea and found the shark that had attacked his nephew.

He picked the shark up and threw it onto the beach. A coastguard shot the fish four times and although this

did not kill it, the shark's jaws relaxed so that they could open them, and reach down into its stomach, and

pull out the boy's arm.

     At the Baptist Hospital in Pensacola, Dr Ian Rogers spent eleven hours reattaching Jesse's arm "It was a

complicated operation," he said, "but we were lucky. If the arm hadn't been recovered in time, we wouldn't

have been able to do the operation at all. What I mean is that if they hadn't found the shark, we wouldn't have

had a chance."

     According to local park ranger Jack Tomosvic, shark attacks are not that common "Jesse was just

unlucky," he says, "evening is the shark's feeding time. And Jesse was in an area without lifeguards. This

would never have happened if he had been in an area where swimming is allowed."

     When reporters asked Jesse's uncle how he had had the courage to fight a shark, he replied, "I was mad

and you do some strange things when you're mad."
