Giant sunfish washes up on beach in South Australia

Pictures of a giant, odd-looking fish have gone viral after it washed up on a beach in South Australia.

Identified as an ocean sunfish by experts, the 1.8m (6ft)-long specimen was first spotted by a group of fishermen driving along the sand.

At first, they mistook it for a large piece of driftwood, said Linette Grzelak who posted pictures of her partner's find on Facebook.

"I didn't think it was real until I Googled sunfish," she told the BBC.

Her partner, Steven Jones has worked as a fisherman for years so "he knew what it was but had never seen one in real life", she said.

"Hence why they took the photos. He said it was extremely heavy and the skin was rough and leathery like a rhinoceros."

The fish was found at Coorong National Park, 80km (50 miles) south of the city of Adelaide. It's believed to have later washed back into the ocean, Ms Grzelak said.
