If you were on the beach and this 20ft creature washed up at your feet you’d probably raise an eyebrow at the very least.

Then you’d tear through the sand, screaming, frothing at the mouth and warning of the apocalypse before being rugby tackled by someone yelling: “Calm down it’s only an OARFISH you chump”.

This undeniably impressive specimen was found in the waters off the main beach of Cabo El Medano, in Mexico.

We're gonna need a bigger beach: An oarfish on the shore

The image was posted on a blog run by Pisces Fleet Sportfishing, which describes a “commotion” at the waters edge, first noticed by realtor Roberto Gonzalez.

The blog says: “His first thought was ‘there’s been an accident’, then he saw three locals supporting what appeared to him as a monster from the deep.

“He ran down to get a closer look and saw them assisting the strange creature, which appeared to be in distress as it struggled for air."

The silver fish, which boasts a bright orange dorsal fin, eventually died, despite repeated attempts to float it back out to sea.

The blog adds: “These are deep water fish, rarely seen, unless they are dying.”

Oarfish, which are also known as ribbonfish, are considered one of the world's longest fish, reaching up to 55 feet and weighing up to 600 pounds.

In Japan, they are traditionally known as "Messengers from the Sea God's Palace" and are believed to be the harbingers of powerful earthquakes, (uh-oh...)

The BBC reports that the fish's extreme proportions, combined with a prominent dorsal fin and undulating swimming motion, could have been the basis for ancient myths of sea-serpents.

The species is thought to live at depths between 700 and 3,000 feet in temperate and tropical waters.

The oarfish's sad demise comes in the same week a giant eyeball washed up on a Florida beach caused a flurry of excitement.

The enormous peeper, still bleeding, was found by a walker on Pompano Beach, and handed to the Florida Fish and Wildlife Conservation Commission who placed it on ice and sent it their labs for possible identification.

Speculation as to the owner of the giant eye ranged from a giant squid, to a whale, a mastodon and a er...Bigfoot, although these were all blown out of the water after the boffins confirmed it had actually come from a swordfish.

On Monday the commission released the following explanation via its website: "Experts on site and remotely have viewed and analyzed the eye, and based on its color, size and structure, along with the presence of bone around it, we believe the eye came from a swordfish.

"Based on straight-line cuts visible around the eye, we believe it was removed by a fisherman and discarded."
