Svergies Television said cameras set up at the Storsjon lake captured footage that shows a blurry, long and narrow silhouette that might belong to the Storsjoodjuret, or Great Lake Sea Monster, Swedish news agency TT reported Thursday.

"(The video) clearly shows that it's warm and is made up of cells, otherwise our cameras wouldn't indicate red, so it can be a sea snake or some other kind of sea animal," a member of the film crew said.

The TV station said 30 cameras will be set up to monitor the lake by 2009 to watch for signs of the beast, which was first mentioned in print in 1635, The Telegraph (Britain) reported Thursday. More than 200 sightings of the Storsjoodjuret have been reported in Sweden.
