Two 5- to 6-foot juvenile sharks spotted swimming outside the surf line at an Orange County beach prompted officials to issue warnings Wednesday.
Signs posted at Surfside Beach warned visitors of the possible hazard a day after the sharks were first seen in the water, according to Chief Joe Bailey of the Seal Beach Marine Safety Department.
A video posted on the department's Facebook page shows one of the sharks swimming off Seal Beach as a paddleboarder nearby watches.
The department began receiving reports of shark sightings Tuesday, but the young sharks disappeared before lifeguards searched the water.
Lifeguards went back out Wednesday to look again. This time, they spotted the sharks swimming outside the surf line.
Bailey said shark sightings are rare.
But when sharks are spotted, they're usually just passing through and headed to another destination, he said.
