Spider silk begins as a liquid protein made by silk glands on the spider’s abdomen. Spiders make many kinds of silk for different uses. As the liquid silk is forced through the spider’s spinnerets, it begins to dry. The spinnerets pull and stretch the silk, creating just the right kind of silk for the spider’s use. Though the result seems thin and weak to us, ounce for ounce, spider silk is stronger than steel.
