A 10-foot Great White Shark had been hooked already by a baited drum line off the coast of Queensland, Australia when it was attacked and bitten by a much bigger fish. Based on the bite marks, the attacker is presumed to be a 20-foot long Great White shark. Swimmers were warned away from the area of Stradbroke Island.
"That cannibal thing is what great whites do; they'll eat anything, including their own kind," Hugh Edwards, a local shark expert, told Australia's 7 News. "It would be sensible not to swim in that area for a little while."Link
