Many fish bones contained in this old washed out dropping.
No interactions present.
Cheers Naturalist Man,
Its a very poor otter spraint, very washed out, basically the remnants of a spraint, I found some pics of much fresher ones since this post, black spraints containing frog and fish bones, they seem to include an awful lot of large insect larvae at times too, eg dragonfly larvae.
