Wrapped up against the gusting Scottish wind, a man is strolling slowly along the jagged shoreline with his lolloping puppy. Anyone passing on the road above would notice him bending over the water, pushing apart the thick brown fronds of rockweed – and then being taken aback to see the “pup” sinuously dive beneath the surface and emerge with a crab in its jaws.

“At a distance, it’s easy to mistake Molly for a dog,” says Billy Mail. “Otters are so shy and elusive it just doesn’t seem plausible that one would be voluntarily going for a walk with a human in broad daylight.”
