GLOBAL ONE NEWS (G1) — When two fishermen in South Australia were strolling along a shore, they spotted something they thought was a shipwreck.


It almost looked like it — until they discovered this “extremely heavy” and “leathery like a rhinoceros” sea creature.


According to reports, the 6ft (1.8m) long giant sunfish has washed ashore at Coorong National Park and was later believed to have returned to the sea.


The girlfriend of one of the fishers who uploaded the photos on Facebook said, “I didn’t think it was real until I Googled it.”


An expert said the sunfish also known as Mola mola is the heaviest bony fish species in the world. They could grow more than 13ft (4m) tall and could weigh over 2,500 kg or (2.5 tons).


Although they could hit and damage boats due to their size, they are said to be harmless to people.
