As I was walking on the edge of the beaver pond on McLane Creek on the boardwalk, I saw a swirling jumble of what at first looked like eels. It was impossible to tell what they were because they were in such continuous motion over, under and around each other slick and shiny gliding and twisting around each other. After a while, while I was taking pictures, noticed little hands and feet sticking up and at times a little frog like head emerged and swirled back down into the mayhem. I have no idea what they were up to and I have not yet identified what species they are, but it the movements were mesmerizing, like tiny furless otters rolling about catching the last of the daylight on their glistening skin.
