Spin Silk
Transcript:
A spider spins its web out of silk that comes from its silk glands. Most spiders have five silk glands, which are located in the spiders abdomen. Each silk gland produces a different kind of silk. Some silk glands produce silk that becomes dry outside the body. Other glands produce sticky silk. Spinnerets are short finger-like organs that the spider uses to spin the silk. They are attached to the rear of the abdomen. The tip of the spinneret is called the spinning field. Each spinning field is covered by as many as hundreds of spinning tubes. Through these tubes, liquid silk flows from the abdomen to the outside of the body. The silk then hardens into a thread. The spinnerets work somewhat like the fingers of a hand. Spiders can stretch, pull and combine silk threads to make threads of different sizes.
