Experts rule out 'great white' in Florida shark attack

The shark that killed a kite surfer in Florida Wednesday was one of several possible species, scientists say. Teeth marks will help them identify the attacker.
Scientists have not yet conclusively identified the species of shark responsible for a fatal attack on a kite surfer off a Stuart, Fla., beach, but they have ruled out any involvement by a great white shark.

There have only been 28 recorded shark bites in Martin County since 1882, says Mark Perry, director of the Florida Oceanographic Society in Stuart. This week’s attack was the first fatality in the county.

The victim, Stephen Schafer, was well known in Stuart, said Mr. Perry, whose office is across the street from Stuart Beach, where the attack took place.

Some media reports speculated that a group of white sharks might have attacked the kiteboarder on Wednesday. Florida-based shark experts say the reports were based on an apparent misquote and media hype.

“Our investigation definitively indicates it was not a great white shark,” George Burgess, director of shark research at the Florida Museum of Natural History, said on Friday.

Instead, he said, an examination of the victim’s wounds suggests that the attacking shark was eight to nine feet long and was more than likely a bull shark or tiger shark.

He said that although the lifeguard who attempted to rescue the kiteboarder saw several sharks nearby, only one shark bit the man. According to officials, there was a very deep and fatal bite to his thigh, a second bite to his buttocks, and a defensive wound to his hand.
Most shark attacks are hit-and-run

Most Florida shark bites are quick nips, like a hit-and-run, experts say. This attack was different.

“The attacking shark really meant business. This was not likely to be a mistaken-identity situation,” Mr. Burgess said. “This was a shark that was attacking with some real meaning.”

Although Burgess was able to narrow the range of potential species involved in the attack, officials have made arrangements to consult a second shark-bite expert to help solve the mystery.

Grant Gilbert, a research scientist in Vero Beach, says he will meet on Monday with the Martin County medical examiner to try to match the victim’s wounds with an extensive inventory of shark jaws. It is a kind of forensic shark-bite version of "CSI."
