Sure everyone's heard of the Loch Ness Monster, but have you ever heard of the Lagarfljóts Worm, Iceland's answer to Nessie? Well you have now!
And not only have you heard about Lagarfljótsormurinn but here's a video which it's claimed shows the mythical monster swimming in Lagarfljót Lake.
Footage appears to show a giant snake (about 90m) swimming against the current in an icy river which runs in to Lagarfljót.
Reports of Lagarfjóts Worm date back to 1345 -- but some critics say this latest example looks more like frozen netting moving in the river.
