Lagarfljót Worm

Also called Lagarfljótsormurinn, Lagarfljot Wyrm, Icelandic worm monster, Iceland lake monster

Iceland's many-humped lake serpent, filmed in a viral 2012 video.

The Lagarfljót worm is a serpent said to live in Lagarfljót, a long, silty glacial lake in east Iceland. It is a 'many humps' monster, said to be longer than a bus, and in some tales it coils up on the shore.

Icelandic annals record a strange sight in the lake in 1345, and the worm appears on 16th-century maps. A folk tale says it began as a small worm a girl put on a gold ring to make the gold grow, and both grew enormous. In 1963 the head of Iceland's forestry service reported a sighting, and in 1983 contractors said a new phone cable laid across the lake bed was found torn in many places.

In February 2012 a farmer filmed a long shape moving in the icy river, and the video went viral around the world. A local committee later debated whether it showed the worm. Skeptics say it is ice or a fishing net.
