The tourists at Alcatraz Island glimpsed something even rarer than Al Capone’s finely-decorated cell or the port-o-potty Sean Connery used when filming The Rock. They saw an actual great white shark leap from the depths and devour a swimming seal like those dirty zebra-striped sandworms of Titan.
Sharks are rare in the bay area because of its estuary conditions, which mix heavy amounts of fresh water with the salty Pacific.
The above video has a nice zoomed-in segment to better see the bloody seal mayhem. The video below is the raw footage. (Ya know: cool footage, slick footage, neat footage. But mainly raw.)
Redditor MikePikeGolly comments: “That seal was filled with strawberry jam!”
