While riding a cable car in Greenwich, a YouTube user named Penn Plate took a video which CLEARLY shows a mysterious creature swimming in the Thames River. Could it be…. GASP… the fabled Loch Ness Monster, down on holiday? Or maybe… as some internet speculators are guessing… GODZILLA? Other theories include crocodiles, a pod of dolphins, a whale, or even a Russian submarine.

From HuffPo:

However, the majority of comments to the video were complaints about the lousy camera work, not about Nessie’s existence.

“The only monster I see is the person who film(ed) this video vertically,” is how one viewer put it.

Another griped, “Of course every cameraman who captures a weird sighting has Parkinson’s.“

Perhaps skepticism is natural considering there have been no confirmed reports of Nessie’s existence since her first modern-day “sighting” in July, 1933.

Wildlife experts haven’t offered any concrete answers about the mysterious object in the video.

Ian Tokelove of the London Wildlife Trust told the Evening Standard he was “not aware of anything that large and moving in the Thames.”

“We had a good look at the footage but it isn’t clear enough to make out what we are looking at,” Tokelove said.

As fun as the idea of Nessie swimming to London sounds appealing, Daily Beast writer Kelly Weill points out just how difficult that would be:

“In order for the Loch Ness Monster to move to London, it would have to swim northeast to the top of Loch Ness, 12 miles through the relatively small River Ness, through the Beauly and Moray Firths, into the North Sea, down the length of Great Britain, and many miles along the Thames. The trip—almost 600 miles by land, and considerably longer by sea—would move the Loch Ness Monster between freshwater and saltwater bodies, a dangerous environmental change that would also likely see the Loch Ness Monster run aground in some shallow inlets.”

Weill adds an important caveat: “The Loch Ness Monster would also have to be real.”
