A group of about 20 sharks should make Northern California beachgoers take a second's pause.
Almost two dozen great whites were spotted by the U.S. Coast Guard Oct. 16 off Pacifica, a coastal community near San Francisco.
The sharks were mostly between 10 and 15 feet long, which is about half the length great whites can grow. But some were at least 18 feet.
