How do spiders produce silk?

Spiders produce silk through specialized glands called spinnerets, located at the rear end of their abdomen. The silk is made from proteins that are liquid at first, but harden when exposed to air. Spiders use silk for various purposes, including building webs, creating egg sacs, wrapping prey, and forming draglines for movement. Different types of silk are produced depending on the spider’s needs, and some spiders can produce multiple threads simultaneously. The strength and versatility of spider silk make it one of the strongest natural fibers known.
