June 30 (UPI) -- Lifeguards at a beach in California posted new advisories after great white sharks were spotted swimming near beachgoers.
Barry Curtis captured drone footage showing a pair of great white sharks, each measuring more than 6 feet long, swimming near a boat towing inflatable rafts in the water at a local beach Sunday.
"I spotted one then I spotted two," Curtis told CBS Los Angeles.
He quickly reported his findings to the lifeguard on duty, who sent out an alert about the lurking sharks.
"He saw that and that's when he got on his radio and said 'I'm gonna call the shore boat and tell them to leave the area,'" Curtis said.
Swimmers were still allowed to enter the water at their own risk, but a lifeguard paddled out to the boaters to warn them that sharks were in the area but not acting aggressively.
Curtis was in disbelief at the sight, as the two large sharks swam within feet of the unsuspecting group of beachgoers.
"I couldn't believe it, there was a small boat towing two inflatable swimming pool swans like big rubber ducks into the shark zone," he told the Orange County Register. "The little white boat was towing a girl in the water right through where these two great whites were searching for food."
Lifeguard Chief Jason Young said sharks have been spotted near the beaches almost daily and encouraged anyone with beach plans to contact the lifeguard department before entering the water.
"Our biggest concern remains ocean conditions," Young said. "But checking the shark status is important, too."
