The life cycle is fascinating. Goes from a kingfisher, to a snail, to the fish: http://www.fish.state.pa.us/images/p...fish/worms.htm
Thanks jcb, most excellent this is it exactly. As a matter of fact the lake that I find these in are in Big Gills that I harvest every year for table fare. They eat a ton of these snails out of this body of water. I've seen their bellies full of these snails.
Thanks again.
