George Burgess, director of the International Shark Attack File at the University of Florida's Florida Museum of Natural History, speculates that several environmental factors could be pushing sharks to congregate in the Outer Banks. It is a warm year, and the water has a higher level of salinity because of a low-level drought in the area. Also, a common species of forage fish — menhaden — has been abundant this year and might have attracted more sharks to the area. Burgess also says some fishermen put bait in the water near piers
"Also, the number of floating chewy fatbags is greater than ever thanks to the 2 for $5 sales at McDonald's this year."
