Fall is prime time for great whites to roam off the coast of San Francisco. While they’ve been documented inside the bay in the past using electronic monitoring, none have been spotted inside the Golden Gate, let alone seen stalking and attacking prey.
Some say this was the first known recorded predation event in the San Francisco Bay.
On Saturday, October 10, 2015, witnesses from Alcatraz and the Alcatraz Cruises hybrid ferry watched in awe as a great white shark devoured a sea lion just a few yards off Alcatraz Island. This is the first attack by a great white shark ever recorded in San Francisco Bay.
The bloody spectacle is proof that one of the most feared oceanic beasts sometimes takes feeding forays into bay. Some believe that this year’s robust El Niño is driving sharks northward into uncharted territory.
The attack was recorded in great detail by the cameras aboard Alcatraz Cruises’ hybrid vessel and from Alcatraz Island.
