California Fire officials said that an approximately 18-foot-long shark was sighted in the waters off Cambria on Sunday afternoon.

Officials after the shark sighting have issued warning signs to beachgoers to be careful along the beach.

However, the beaches will remain open but authorities have issued shark warnings to swimmers to stay out of water between Cambria and San Simeon.

The grey-colored shark was sighted at about 3 p.m. on Sunday about 50 yards off Leffingwell Landing.

According to California Department of Forestry and Fire Protection news release issued on Monday afternoon officials have determined the report to be a credible.

Despite the frequency of shark sighting experts believe note that the shark’s attacks are uncommon.

The shark spotted on Sunday is the sixth credible report of a shark in the waters off San Luis Obispo County in less than two months, Cal Coast News reported.

Cambria is a seaside village that is situated between San Francisco and Los Angeles on the California State Route 1. Cambria is also a popular tourist destination.

Pertaining to a report from the International Shark Attack File, which is a project of the Florida Museum Of Natural History, states that the odds of being attacked by a shark are 1 in 11.5 million and that of being killed is less than 1 in 264.1 million.
