A classic circular form spider's web Infographic illustrating the process of constructing an orb web. A spider web, spiderweb, spider's web, or cobweb (from the archaic word coppe, meaning 'spider') [1] is a structure created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey.
The building of a web is an engineering feat, begun when the spider floats a line on the wind to another surface. The spider secures the line and then drops another line from the center, making a "Y". The rest of the scaffolding follows with many radii of nonsticky silk being constructed before a final spiral of sticky capture silk.
Most external appendages on the spider are attached to the cephalothorax, including the eyes, chelicerae and other mouthparts, pedipalps and legs. Like other arachnids, spiders are unable to chew their food, so they have a mouth part shaped like a short drinking straw that they use to suck up the liquefied insides of their prey.
Schematic of the spider's orb web, structural modules, and spider silk structure. [15] On the left is shown a schematic drawing of an orb web. The red lines represent the dragline, radial line, and frame lines. The blue lines represent the spiral line, and the centre of the orb web is called the "hub".

Web-building spiders have poor vision, but are extremely sensitive to vibrations. [13] The water spider Argyroneta aquatica build underwater "diving bell" webs that they fill with air and use for digesting prey and molting. Mating and raising the offspring happens in the female's bell.
