The Graphic: The colors lines represent actual sharks from 2000-2008. The gray area represents the extrapolated ranging of all great whites in the area. There is no blow-up of the bay, but supposedly they roamed inside the Golden Gate.

The Study: According to a Stanford University-led study released Tuesday, great white sharks occasionally stray from their Northern California feeding grounds for jaunts under the Golden Gate Bridge into San Francisco Bay, apparently in search of snacks. The sharks lived in the deep ocean near Hawaii between January and July and in Northern California between August and December. The scientists tracked the snaggly toothed predators between 2000 and 2008 from the Bay Area to San Diego, Hawaii and back as the sharks followed a surprisingly precise route in a strict time frame.

My take: There are thousands of seals in the Bay. However, the water is comparatively cloudy and noisy. This relative different probably ruined the hunting efforts of the sharks while they were in the Bay. That said, it’s only a matter of time until there is a great white attack in the Bay — shiver.
