Shark attacks up across the U.S.

Lately, beachgoers on Long Island have had to be on the lookout for more than just sun and fun. 

There have been five shark attacks in just the last two weeks. Among them was a Fire Island lifeguard who was bitten on the foot. At one point, two people were attacked on the same day.

And an Arizona tourist was bitten on the hand and buttocks while standing in waist deep water, suffering wounds to his lower leg while he surfed.
