On Saturday, 20-year-old surfer Emily Comfort was bitten on her left hand and wrist, according to Volusia County Beach Safety.
Less than 24 hours after the first two bites, 51-year-old Peter Bourbeau was standing in knee-deep water when his right foot was bitten by what he described as a 4-foot-shark, Volusia County Beach Safety said.
According to the International Shark Attack File, Volusia County has recorded 303 shark attacks -- the most in the United States -- since 1882.
The second closest is Brevard County, Florida, with 147.
Of the 1,441 confirmed unprovoked shark attacks in the United States since 1837, Florida dominates the list, with 828 recorded attacks.
