The Lagarfljot Worm or Iceland Worm Monster is a giant worm-like creature that lives in the Icelandic lake of Lagarfljot. It is described as being longer than a football field, 200 feet long. Sometimes, it is even reported as being as long as Lagarfljot lake itself! This worm has many humps as it swims through the murky water, often looking quite serpentine. It has also been reported coiled up or slithering up trees. It lives in the murky waters of Lagarfljot lake, Egilsstaoir, Iceland. Its first reported sighting was in 1345, and its most recent sighting was in 2012, which either means these creatures have an extremely long lifespan (700+ years), or there is a small population living in the lake. There is also a legend that it was a lindworm thrown into the lake.
