#LoughFoyleMonster - Could Lough Foyle be hiding its very own version of the legendary Lough Ness Monster? As the video above attests, some witnesses to a mysterious sighting in the lake recently seem to think so.

According to The Canadian, a glimpse of what appears to be a large rock-like creature just breaching the surface of the water was captured by a group on the lough.

“It's really difficult to determine what species of creature it was," said one of the group. "I really don't think this can be a whale. I've seen whales, but I've never seen one swim like this before. Also, the pattern on it doesn't really look like it’s a whale.”

But before we all get too excited, consider that the group who made the video admitted that they were shooting for a student film called Fishing With David Lynch - a film and TV director well known for his other-worldly twists on reality.
