Out in the snow today I saw a little black creature skittering across the surface. My cat like instincts eventually had me holding a mole in my right hand. I gently lowered him into a bucket and went to get the camera.
If one of these tried to cross a slow pool with a big trout residing in it, particularly at night, I bet that it would not reach the other side.
After I got the picture I was looking for, I let him continue with his dark underground life.
