Of all the animals that could kill you in Australia, sharks have gotta be the scariest. Have you seen Jaws: The Revenge? That 2.4 IMDB rating is absolutely frightening.
But for fishermen in South Australia, the nightmare became reality when they reeled in a 10ft whaler shark, which they proceeded to wrestle on the shore to take its measurements. Because Australia. Eventually, the guys who caught the 430-pound creature -- which was so heavy it snapped the fishing rod -- released it back into the water. The beast swam away and didn't bother attacking its hunters, but you never know... maybe it's just plotting its revenge. Ask Roy Scheider.
