Web

Some spiders build webs. The yarns of these webs, consisting of silk, are produced in special glands located in the abdomen of the spider. A silk is expelled liquid through tiny little tubes, on the back of the abdomen. Upon leaving, silk solidifies immediately on contact with the air, forming wire urn with which the spider produces the web. The webs are used to trap small animals, mostly insects, which feed these spiders, they kill them with chelicerae. Each species has a spider web pattern characteristic, whereby one can often classify it.
