Spinneret
Definition:
(n.) One of the special jointed organs situated on the under side, and near the end, of the abdomen of spiders, by means of which they spin their webs. Most spiders have three pairs of spinnerets, but some have only two pairs. The ordinary silk line of the spider is composed of numerous smaller lines jointed after issuing from the spinnerets.
