Mark McGrouther of the Australian Museum Fish Site says: "The crested bandfish is pretty neat but the really amazing story is to do with the cookie shaped wounds on its side.
"These wounds are caused by the Cookie-cutter shark, a small beast that has bitten cookie-shaped plugs of 'flesh' from a range of larger fishes, mammals and even the sonar domes of submarines.
"And finally, it's 'big brother' the Large-tooth Cookie-cutter Shark has an absolutely unbelievable set of choppers."
