 Officials say a 26-year-old man was bitten on his foot in the waters off Florida's new Smyrna Beach late Friday afternoon. It was the second shark bite within 24 hours at the beach. Elsewhere, swimmers were sent rushing to get out of the water at South Padre Island along the southeast coast of Texas on the 4th of July. Texas Parks and Wildlife officials say two people were bitten there and two others had serious encounters with what is believed to have been a bull shark.
