A rare ‘doomsday’ oarfish, measuring nine feet in length, washed ashore on a Tasmanian beach.

Dog walker Sybil Robertson found the sea monster on Ocean Beach on the Australian island’s western shore on Monday.

Seeing oarfish outside of their normal environment in the ocean’s depths is frequently considered as a bad omen.

Robertson, who estimated the fish was about 9ft long, said of the rare find, “It was fantastic. I just knew it was something unusual and weird.”

The dogwalker claimed that until she posted pictures of the massive silver fish washing up on the sand on a local Facebook group, she had no idea how uncommon the fish was.

Following a re-share on the social media site Reddit, the picture swiftly gained popularity as a number of online users commented on the fish’s possible significance, which has been connected to foretelling disastrous occurrences in Japanese folklore.  

“The ocean is very unhappy with humanity’s disdain for it,” one user commented. 

Another said, “We’re seeing a lot of these rare “doomsday” fish washing up these days, aren’t we?.” 

“The world DOES seem to be ending more frequently lately,” a third wrote.

Oarfish have a maximum length of 36 feet and a maximum weight of 441 pounds.

According to legend, they predict earthquakes and other natural calamities.

Months after an oarfish washed up on a Canary Islands beach, Tasmania saw its unusual sighting.

When bathers found the marine creature on the Lanzarote shore of Playa Quemada on February 10, it caused panic on the internet.

A man approaches the silver fish to save it in a video of the sea monster that went popular on Instagram.  

Only a few weeks had passed since a similar fish on a Mexican beach raised alarms before the sighting on the Spanish island.

On the southernmost edge of the Baja California Peninsula, surfers noticed the monster.

The enormous fish, which was roughly the length of a surfboard, had a silvery-blue body and a beautiful red fin that ran down its back, but its tail was wounded.
