Came across these last night on a small mud bank next to a stream that runs through a small gully on one of my permissions.
Be around 1.5 - 2 inch's broad. The stream is maybe 5ft wide with the odd pool, maybe 18 - 24 inches at its deepest. Never seen any fish in it though. The gully's whins provide cover for badgers and fox. On the second picture you can just make our a fifth toe on the right.
I am thinking otter but am interested to know what you think.
