Why do spiders produce silk in so many different forms?
Quick Answer
Spider silk is a family of specialized materials used for webs, egg sacs, draglines, and prey capture. Different glands produce silks with different properties.
The Full Story
Spiders do not make one universal silk; they make several types, each tuned for a specific job. Some silks are sticky for trapping prey, while others are strong and stretchy for support lines or wrapping eggs. Silk originates in different abdominal glands and is drawn through spinnerets at the rear of the body. Researchers have found spider silk to be remarkably strong and versatile, inspiring biomaterials research. This diversity helps spiders survive in very different hunting styles and habitats.
