See the silk coming from the spinneret glands located at the tip of the abdomen. A spider web, spiderweb, spider’s web, or cobweb (from the archaic word coppe, meaning “spider“) is a device created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey.There are several different sorts of web – the sheet web, orb web, tangle web, funnel web, tubular web and dome or tent web. The most common type of web that is seen around the home is the orb web, so called because of its circular shape, resembling a giant wheel. It is an immensely strong webSeveral different types of silk may be used in web construction, including a “sticky” capture silk, or with “fluffy” capture silk, depending on the type of spider. Webs may be in a vertical plane (most orb webs), a horizontal plane (sheet webs), or at any angle in between. Most commonly found in the sheet-web spider families, some webs will have loose, irregular tangles of silk above them. These tangled obstacle courses serve to disorient and knock down flying insects, making them more vulnerable to being trapped on the web below. They may also help to protect the spider from predators such as birds and wasps.
