MYSTERY surrounds a grisly discovery made by two fishermen in the estuary on Monday night.
A dead dolphin was found near Boundary Island with two-inch bite marks around its body and other lacerations.
The following morning DEC volunteers removed the dolphin.
Shark and Ray Sustainability senior research scientist Rory McAuley said it appeared the bite marks on the dolphin had been caused by a great white shark. “There is considerable post-injury deformation on the dolphin’s body however the shape of the primary bite arc would indicate it was caused by a white shark,” Dr McAuley said.
A spokesperson for the Department of Fisheries said the department could not be certain if the attack on the dolphin had happened in the estuary or in the ocean.
The spokesperson said they were not sure if any tagged white sharks had been tracked in the area recently.
