spider web, spiderweb, spider's web, or cobweb (from the archaic word coppe, meaning spider) is a structure created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey.Spider webs have existed for at least 100 million years, as witnessed in a rare find of Early Cretaceous amber from Sussex, in southern England.vMany spiders build webs specifically to trap and catch insects to eat. However, not all spiders catch their prey in webs, and some do not build webs at all. The term spider web is typically used to refer to a web that is apparently still in use (i.e., clean), whereas cobweb refers to a seemingly abandoned (i.e., dusty) web.[3] However, the word cobweb is also used by biologists to describe the tangled three-dimensional web of some spiders of the family Theridiidae. While this large family is known as the cobweb spiders, they actually have a huge range of web architectures other names for this spider family include tangle-web spiders and comb-footed spiders
