Shark bites on east, west coasts frighten swimmers

The boy could be heard crying, "I want my mommy," as lifeguards treated the wound on his right leg. Splotches of blood dotted Florida's Neptune Beach after the boy was loaded into an ambulance.

Police say the shark in this case was between five and six feet long.

In Newport Beach, Calif., lifeguards pulled a woman from the surf with large bite marks on her torso and shoulder. She was taken to a local hospital and a two-mile stretch of Corona del Mar Beach was evacuated.

Despite the fear factor, shark attacks are incredibly rare. Statistically, a person is much more likely to be struck by lightning.
