"I couldn't believe my eyes when I saw this jet black thing, about 45-feet (15 meters) long, moving fairly fast in the water," said Gordon Holmes, the 55-year-old a lab technician from Shipley, Yorkshire, who took the video this past Saturday.

He said it moved at about 6 mph (10 kph) and kept a fairly straight course.

"My initial thought is it could be a very big eel, they have serpent-like features and they may explain all the sightings in Loch Ness over the years."

Loch Ness is surrounded by myth and mystery, as it is the largest and deepest inland expanse of water in Britain. About 750 feet (230 meters) to the bottom, it's even deeper than the North Sea.
