Watch: Weird 'Mystery Creature' Filmed Swimming in England's River Thames

A puzzling piece of footage from England shows a weird 'mystery creature' that was spotted swimming in the River Thames. The odd scene was reportedly filmed by Ryan Linehan as he and his parents were walking along the famed waterway that stretches through the community of Old Windsor. Their stroll took a strange turn when they noticed the head of a dark creature bobbing up and down as it swam in the river. "It looked slightly furry in its appearance, and it had quite a flat nose," the bewildered witness recalled, "I'd say in length, it was the size of a medium to large dog."
