They are Parasitic though; them being parasitic on humans are known as Ascarids,filarias, hookworms, pinworms, and whipworms.  One form of the Nemotoda is entirely dependent upon fig wasps, which are the sole source of fig fertilization.  

Some of the puzzles that people list for the public get indexed by the search engines (like Google). Some people find those puzzles and cannot figure out how to make a puzzle of their own. So this page now has the navigation sidebar.

There are now buttons on the puzzle so that you can get a clean page, in either HTML or PDF, that you can use your browser's print button to print. The PDF format allows the web site to know how large a printer page is, and the fonts are scaled to fill the page. The PDF takes awhile to generate. Don't panic!
