Uving species whereas the large opaque forms depart most widely from that type. In general organology, microscopic structure of cells and their arrangement in layers, as well as in fundamental features of reproduction and development, the parasitic nema- todes agree substantially with the free-Uving forms and manifest their recent differentiation from them. The anterior end or "head" of a nematode is usually slightly truncated or bluntly rounded and shows under a lens the presence of lips, papillae, spines, teeth and other special structures. In reality the numerous modifications of the anterior end may.
