Beaches north of Miami remained largely empty on Thursday as panic spread after a bizarre incident in which sharks attacked and killed a kite-surfer off the eastern coast of Florida.
Stephen Schafer, 38, was spotted by a lifeguard as he was floating encircled by sharks and screaming for help off Stuart Beach, 150km north of Miami, police said.
The lifeguard brought the man to shore on his board and tried to resuscitate him on Wednesday before he was rushed to hospital where he died.
The beach, which has never before recorded a shark attack, was swiftly closed after the incident, but reopened on Thursday as shark experts called for calm.
