Footage has emerged showing what appears to be a giant serpent swimming against the current through an Icelandic lake.
According to legend, the monster grew from a tiny magical worm that had been placed in a ring of gold to make it grow, IceNews said.
Instead of enlarging the gold, the worm grew into a giant snake and both it and the ring were tossed into the Lagarfljó, where it continued to grow to monstrous proportions.
Sightings of the worm are considered to be a bad omen.
The video was shot by Hjörtur Kjerúlf and was first posted on ruv.is.
Skeptics have claimed all the video shows is a torn fishing net that froze in the 140km long river.
