A great white shark that washed up on a Victorian beach is likely the victim of a pod of killer whales.
The three-metre shark was found partially eaten on the shore at Cape Bridgewater, southwest of Portland.
The head and tail of the great white was intact, but there was little left of the midsection of the predator.

Wildlife scientist Vanessa Pirotta said the killer whales were after one thing.
"In this case they are really interested in shark liver," she told Today.
"It seems to be the juiciest part."
Killer whales are also known to target humpback whales just to eat their tongues.
"There is science going on right now to find out why they are such picky eaters," Pirotta said.

Pirotta said killer whales were "very strategic and clever".
Photos of the shark's remains were posted on the Facebook page of local business Portland Bait and Tackle.
"This is equal parts cool and terrifying," the images were captioned.
Locals reported seeing a pod of killer whales, otherwise known as orcas, in the past few days.
Cape Bridgewater is better known for the presence of other marine mammals, thanks to a colony of hundreds of fur seals.
The term orca has risen in popular use in recent years, because the term killer whale is a misnomer.
Killer whales are considered to be part of the dolphin family.
Though the term orca derives from a term used in ancient Rome to describe other whale species.
Killer whales are unusual as sea creatures for their style of feeding, hunting as a pack.
They are known to eat fish, sharks, rays, dolphins, porpoises, seals, sea lions, penguins and even larger whales.
While they typically will seek to target whale calves, there have also been documented hunts of sperm whales, humpback whales, minke whales and blue whales.'
