Jaws strikes again

It was a routine trip to the San Francisco Bay for Joey Gamez of Golden State Sportfishing, one of countless morning excursions he's taken clients on over the last 20 years. But circumstances shifted into something like a Steven Spielberg film when an unknown force from the blue depths below began to yank on his fishing line.

"It was almost like hooking onto a Volkswagen that was a hundred feet deep," Gamez told CBS. All he could do was try to hold onto the rod and reel as the boat itself began to lurch forward.

The looming pressure wasn't an anchor, or even a sturgeon or seven-gill shark like he'd caught before, the latter of which can weigh up to 700 pounds. Gamez's knuckles began to turn white as his fishing rod bent downward and curved into a candy cane-like shape. "This is probably the biggest fish I've hooked into out here," he said aloud.

It was a Great White Shark.

In the meantime:

San Mateo officials issued a warning Thursday after receiving multiple reports of great white shark sightings in Half Moon Bay. It's likely due to warmer water temperatures, which scientists say have been steadily increasing since 2014.

Warmer water allows younger sharks, normally native to southern California, to travel farther north for feeding.

Earlier this March, a man says he made eye contact with an 18-foot-long great white shark at Mavericks before it began to beeline toward a group of surfers. Just last month, another was seen in Bodega Bay, delaying water training plans for the Sonoma County Sheriff's office.
