I took some pictures but the worms are to small in diameter to be able to see in the pics. I can see some that are atleast two inches long but only as thick as about a 1/3 of the thickness of mechanical pencil lead. If I can get some pics to turn out I will post them because there is a cluster of about 20 small worms that are sticking out of the gravel about 1/2 inch and they are waving back and forth. They go down when a crawdad goes over them, but they come right back and start waving again. It's kind of weird. Oh well, that's it for now.
