Lifeguards closed a beach in Ocean County, N.J., Wednesday morning after surfers spotted sharks in the water.
Two five-foot sharks swam off Seaside Park for several hours, lifeguard captain Joe Gomulka said. Swimmers were allowed back into the water about 12:30 p.m., after the sharks moved north, he said.
"We're still trying to figure out what kind of sharks they were," Gomulka said. The beaches will be open Thursday, he said.
