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.
