Australian authorities are warning people to stay out of the water around Stradbroke Island near Brisbane unless they want to risk meeting a great white shark big enough to bite another great white nearly in half. Experts who examined the remains of the other shark believe its rival must be around 20 feet long, judging from the huge size of the bites.
"Whatever attacked and took chunks out of this big shark must be massive," one surfer told Brisbane's Courier-Mail. "I've heard about the big one that's lurking out there somewhere. We're all being very, very cautious."
