A video which seems to show a “strange creature” in the Thames has divided the internet over whether it is a whale, a submarine or the Loch Ness Monster.
The YouTube clip, taken from the Emirates Air Line cable car, shows a long dark shape which appears to have two humps emerging from the river.
After a brief glimpse, it disappears back beneath the murky water in front of The O2 in Greenwich.
YouTube user Penn Plate, who took the video, wrote: “Something huge was moving under the water and then briefly surfaced.
“Are there whales in the Thames?? Or is it some weird submarine?”
Viewers are undecided what the strange sight might be.
One wrote: “If you slow it down enough and pause it, kind of looks like a pod of dolphins or porpoises.
“But there's still a huge shadow under the water that just looks like one giant sea creature, and it's way more exciting to think that it's some crazy undiscovered ancient beast that's probably going to crawl out of the river and start eating people and toppling buildings, so I'm gonna go with that. ”
Others speculated it might have been the mythical Loch Ness Monster a long way from home.
“Straight up godzilla’s tail right there,” wrote another viewer.
But many people are sceptical about the video and questioned why it had been filmed in such a clumsy way.

Last year, the Standard reported that more than 2,000 seals and 450 porpoises and dolphins have been spotted in the Thames over a decade.
