I don't know why they all assume it must have been a Great White when none have ever been seen anywhere near here and Porbeagles and Makos have. 1ft bite radius means its a bloody small Great White.
Also why did the shark not eat the seal? I always thought when a surfer gets bitten its the shark's way of testing if the surfer is food or not, and after the shark takes a bite it knows the surfer is not a seal so it lets the surfer go.
Why did it let the seal go? I mean thats what sharks eat isn't it?
