That is, until a lifeguard on San Diego's Mission Beach spotted a 18-inch dorsal fin skimming along the water around noon on Thursday, attached to what he reckons was a "12-to-15-foot" Great White Shark. The beach was immediately evacuated, and then a search mission was undertaken:
Lifeguards in three motor launches and two personal watercraft were patrolling the waters near the shore, attempting to locate the shark. A helicopter was also searching for the fish.
All together now: "We're gonna need a bigger boat."
