40-year-old swimmer has injuries from the teeth after 6 to 7 foot long juvenile great white. >> when i saw the injury, it wasn't a full size bite and it was on the torso just under the arm. >> reporter: great whites are common in the waters off manhattan beach. eric martin who works at the round house aquarium on the pier says that this may have been what's known as a response bite. >> it's where the shark is hooked in the lip and he's trying to shake the hook, his mouth a open shaking his head. his teeth are coming out and we think the swimmer just happened to be at the wrong place at the, say, wrong time. >> our thanks to melissa mcbride with kabc for that report. >> after all of these bouncing houses have been swept up and blown away, would you still hop into one? >> it happened again. and wait till you hear what happened just before the bounce house went airborne. and remember this?
