Several onlookers in Pacifica's Linda Mar Beach spotted what they described to be a great white shark attack and devour a sea lion about 200 yards from the beach on Monday afternoon. The shark was reportedly approximately 18 feet long or larger, and half a dozen witnesses reported seeing it jump out of the water from various vantage points, splashing "blood all over the place."

Warning signs have since been posted in the area, but surfers were back in the water within a couple of hours since the shark had already eaten and was probably full for the time being. [KTVU]
