Mysteries of Giant Fish, Loch Ness and Sea Serpents


The discovery in Fall 2013 of a monstrous fish off the Southern California coast had people buzzing. Photos of people holding a long piscine monster spread around the Internet; there are of course many fake “big fish” photos floating around, but this one was not a Photoshop job, nor a hoax.

As a Discovery News story noted, “The staff and kids at a Southern California educational facility got quite a surprise when an 18-foot-long (5.5 meters) serpentlike sea creature washed up near the shore. While swimming in about 20 feet (5 meters) of water, dive instructor Jasmine Santana saw a large, silvery, slender figure on the sandy bottom on Sunday.” It took 25 people to pull the bony monster with reddish fins out of the water and pose it for photographs.

The creature — not a true sea monster but as close to one as most people will ever, or would ever, want to get to one — was a rare animal called an oarfish. Because they typically live deep in the ocean, little is known about them, though scientists believe that they may grow to be twice as long as the most recent specimen.

Seeing the amazing photograph led many to wonder if these marine monsters might be mistaken for lake monsters or sea serpents. Could an oarfish (or, more realistically, a family of them) be responsible for sightings of Scotland’s famous Loch Ness monster over the years? It’s a tantalizing possibility, though scientifically unlikely.

For one thing, oarfish, whether small or huge, are not found in Loch Ness. Oarfish also tend live in temperate to tropical ocean waters and the most famous lake in the Scottish Highlands would likely be too cold for them. Furthermore, oarfish are saltwater fish, while Ness — fed by several large rivers — is freshwater. Though some marine animals, such as several species of dolphins, are known to have adapted to freshwater, oarfish are not among them.

Sharks as Monsters

If not an oarfish, then what? In 2012, a researcher offered a new theory about what real animal might be behind some of the Loch Ness reports. Bruce Wright, a senior scientist at the Aleutian Pribilof Island Association, wrote an article suggesting that Nessie sightings may in fact be sleeper sharks, which can reach 20 feet long and weigh more than 4 tons. Wright theorized that the sharks might enter Ness through rivers connected to the ocean.
