Two Great White Sharks Filmed Feasting on Whale Carcass By Stunned Fishermen: 'I've Never Seen Anything Like That'

Two great white sharks were filmed feasting on the carcass of a sperm whale by stunned fishermen in Australia.

Jesse Gibson said he and his friend James Powley were fishing off the coast of Yallingup in Western Australia over the weekend when they came across the floating carcass of a sperm whale.

Gibson wrote on Facebook that two sharks then turned up and started circling his boat then started tearing into the whale carcass.

Gibson posted clips of the feeding frenzy on his Facebook page, describing it as a "once in a lifetime" moment.

"No f***ing way," one of the men can be seen saying as the two sharks are seen ravaging the whale carcass.

"Got the pleasure of finding a dead sperm whale floating around in the deep blue yesterday," Gibson, who is from Busselton in Western Australia, added in a caption alongside the videos.

Gibson added that things got "crazier" when two great sharks—measuring at least four meters—started circling the carcass before eating it. "Once in a lifetime kinda stuff! The ocean never ceases to amaze me," he wrote.

He and Powley were around seven miles off the coast off Yallingup on Saturday morning when they came across the whale, 7News reported.

Gibson, 21, told the website that he's been fishing for years and had never seen anything like it in the water before. He added that the two sharks circled his small boat for around 10 minutes, before spending 40 minutes feasting on the whale.

"I've never seen anything like that, I don't think many people ever will, it was a once in a lifetime—it was gnarly," Gibson told 7News. He has been contacted for additional comment.

The Sharksmart website said a whale carcass had been reported at Southgate Dunes Beach in Western Australia last week.

In an update on Sunday, it said officers from the Department of Primary Industries and Regional Development (DPIRD) had found the carcass had since washed out to sea.

People were urged to remain cautious as residue from where the carcass was beached could still attract sharks to the area. The DPIRD has been contacted for comment.

Meanwhile, on Monday, a man survived a shark attack while swimming in the Great Barrier Reef.

Authorities said the man, who is in his 30s, was bitten on the leg by a shovelnose shark while in waters off the coast of North West Island in Queensland, but managed to escape with only minor injuries.
