Norway's own Loch Ness Monster!

What does anyone think this is? It was observed in Hornindalsvatnet, Europe's deepest (at 514 meters) inland lake, which lies in the mountains south of Sognefjord about 3 hours drive north of Bergen  It was seen on Wednesday evening by 3 grown men and they are absolutely convinced they have seen a 'lake worm' - I guess you could say it is the equivalent of our Loch Ness monster.

The picture was taken at 9.30 p.m. - as you can see it is still very light in Norway at that time, although the evenings are beginning to draw in gradually. Norwegian legend has it that these creatures like to 'bathe in the light of the full moon' and it was a full moon that night!

Apparently Hornindals lake has a reputation for harbouring some kind of monster, and there have been several sightings dating back hundreds of years!  So is this a fresh water sea serpent or what?
