This is just the external appearance of these microscopic crea-
                  tures. The body of this creature, which is invisible to the naked eye
                  but which lives alongside us at every moment, also has an inside.
                  This mite, the existence of which we were perhaps unaware of un-
                  til now, possesses quite wide-ranging internal organs:
                       Some mites can live in water as well as on land, but those that
                  live on land breathe through a respiratory tube, 103  immediately next

                  to which is their feeding tube. Some mites have feeding apparatus
                  sharp enough to pierce plant cells, with which they can easily suck
                  up juices from the plant. 104  In some mites, a rather advanced nerv-
                  ous system surrounds the feeding tube. The microscopic invisible
                  mite even has a brain. A series of nerves emanating from the brain
                  operate the legs, muscles and the reproductive system. The nerves in
                  the mouth organ are controlled by another part of the brain.

                       Of course, the mite must have a digestive system to obtain
                  nourishment from what it eats. This consists of a pharynx at the
                  front, a long, narrow esophagus, a stomach, a short intestine and an




                                                     Mites possess perfect internal or-
                                                     gans, legs with nerve and muscle
                                                     systems, and even a brain.
