Has anybody observed this before? I observed a young slug in my greenhouse suspended on a silk line it was extruding itself. The animal was three quarters of an inch, young enough I could see its insides. I wondered if it was using a spiders drop line, but there was no line below the slug. Watching showed that indeed, the line was from the slug's tail end. I am just wondering if an adult slug can do the same. Oklahoma City, Ok.
