We received an interesting question a while ago about a “gross worm thing.” We were told to direct our attention to the gross worm on the paper towel in the photo, which sounds reasonable, except for the fact that we were given no photo to examine. All we know about the worm is that it is “gross,” about an inch long (2.5 centimeters), and doesn’t have any legs. Obviously, this isn’t much information to work with, but we can say a couple of things about the gross worm, and in doing so we’ll at least limit the range of possible creatures that she found.
