 This is a known mindless killer. The shark is smart. It pitches up at the peak of the turtle nesting season, and simply waits for the tide to deliver its food.-Ah, look at that so distinctive...have the boat. Tigers are a big fan with all manner interesting things in their stomaches, and as an opportunist predator, she's coming in and just have a little look at the boat and a little look at me. Just snatching the boat, she's using the nose and all the senses packed into the nose to figure out what we are, what I am. And now she's heading back to the calves, I hope. Watch his bite! It's grip. What she's doing now is sawing, using the weight of the body, she's huge havoc animals.
