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.
Some spiders that do not spin actual traps build alarm webs that the feet of their prey (such as ants) can disturb, cueing the spider to pounce on prey or flee a formidable intruder. [38] Pheromonal trails Some wandering spiders leave a largely continuous trail of silk impregnated with pheromones that the opposite sex can follow to find a mate ...
Spiders produce silk using special organs called spinnerets, located typically on the underside of their abdomen. They look a bit like an icing nozzle The 7 Types of Spider Webs and the Incredible ...
The web of a funnel-web spider Tegenaria duellica. Many spiders, but not all, build webs. Other spiders use a wide variety of methods to capture prey. Web: There are several recognised types of spider web. Spiral orb webs, associated primarily with the family Araneidae; Tangle webs or cobwebs, associated with the family Theridiidae; Funnel webs,
Spiders also have several adaptations that distinguish them from other arachnids. All spiders are capable of producing silk of various types, which many species use to build webs to ensnare prey. Most spiders possess venom, which is injected into prey (or defensively, when the spider feels threatened) through the fangs of the chelicerae. Male ...

Spiders spin silken webs to capture flies and other tiny prey. They’re also trapping a wealth of DNA from the surrounding environment, a hidden resource that Australian scientists said could be ...
Spiders often attach highly visible silk bands, called decorations or stabilimenta, to their webs. Field research suggests that webs with more decorative bands captured more prey per hour. [ 84 ] However, a laboratory study showed that spiders reduce the building of these decorations if they sense the presence of predators.
