What is a spider silk web?
Quick Answer
A spider silk web is a structure made from silk that spiders use to catch prey, move around, or protect eggs. Different spider species make different kinds of webs.
The Full Story
Spider silk webs are one of the most remarkable structures in nature. Spiders produce silk from specialized glands and use it for prey capture, safety lines, egg sacs, retreats, and sometimes ballooning through the air. Orb webs, made by spiders such as garden orb-weavers, are the familiar wheel-shaped webs designed to trap flying insects. Other spiders build sheet webs, cobwebs, funnel webs, or no web at all. Spider silk is lightweight, strong, and highly elastic, which makes it a subject of scientific and engineering interest.
