Worm ID


New member
Is there a link to a site that has Worm ID? I just saw a worm that is about the diameter of a pencil lead. It is black on the top and white on the bottom. Looks like maybe a filter feederbecause it puts out tentacles off and on. I cannot get a picture because it is partly in a hole in a rock. Anyone know what this could be?
Thanks for any help!
