Does Silk Come From Spiders
In general, all spiders produce silk. And, this type of silk is used for climbing, to make webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. Thus, spider webs are one of the strongest fibers in nature. Most spiders have 4 or more openings or glands on their abdomen called spinnerets. Spider silk is about 5 to 6 times stronger than high-grade steel by weight. Spider silk is more durable and elastic than any known natural or synthetic fiber on Earth.
