Dozens of sharks spotted feeding off dead whale in Western Australia

Drone vision has captured a shark feeding frenzy off the coast of Western Australia.

Australian travellers John Cloke and Indy Crimmins were fishing off Norman's Bay two weeks ago when splashing caught their curiosity.

They sent up a drone and what they discovered blew them away.

They captured dozens of hungry whaler sharks feasting on a dead whale.

Fisherman and writer Mike Roennfeldt said the feast was like nothing he'd ever seen before.

"It seems to me you get two, three, four, five sharks — occasionally you get more — but that's an awful lot on this one," he said, describing the meal as like "you and I having a vanilla slice".

"You know, it's pretty good," he said.

Roennfeldt, who believed some of the larger sharks might have been great whites, said it was nature "in the raw".

"If you haven't been up close like that sort of thing, yeah it's pretty confronting and exciting at the same time," he said.
