The Miracle of Creation 105

Spiders are very sensitive to vibrations on their webs. The female Black widow
spider is able to tell whether the source of the vibrations on its web is an insect
caught on it, or a male coming to mate.

The Body
The spider's body is composed basically of two parts, the combined

head and thorax (cephalothorax), and the abdomen. The head and thorax
have eight eyes, eight legs, two venom fangs and two feelers. At the tip,
the soft and elastic abdomen are spinnerets and holes for breathing
systems. The cephalothorax and the abdomen are joined by a small stalk
called the "pedicel." No other living creature's waist is as thin as the
spider's. Through this narrower than 1mm stalk pass the digestive tract,
veins, windpipe, and nervous system. To put it more generally, there is a
special linear system joining the two halves of the spider's body. These
lines form a link between the splendid mechanisms within the structure

of the spider's body (venom glands, silk-producing glands, the whole
body's nervous system, breathing and circulation systems) and the brain.
