A 9-year-old boy and an adult were apparently bitten by sharks off the beaches of a barrier island, authorities said.
The attacks happened within an hour of each other Saturday in the water along Hutchinson Island in St. Lucie County on Florida's east coast.
The boy was bitten on his right buttock and thigh at Waveland Park, St. Lucie County Fire District spokeswoman Catherine Whitaker said.
About an hour later, a 30-year-old surfer was bitten on his right ankle, causing a deep wound serious enough that he was hospitalized for observation, Whitaker said.
Authorities did not release the name of either victim.
But both attack were not considered life-threatening.
