A spider’s web has an interesting design. A spider uses silk, produced in its abdominal glands, to make webs. It pushes out this silk as liquid through several small holes found at the tip of the abdomen. This liquid becomes solid in the presence of air. The web thread is of many kinds. For example, sticky silk helps to catch prey; the non-sticky has strong spokes, and silks are extracted from the cocoon. Different types of spiders spin different kinds of web. The main function of a spider’s web is to catch prey. Spiders make a nest of silk to protect their eggs.
