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.

[1] This diverse, globally distributed family includes over 3,000 species in 124 genera , [ 2 ] and is the most common arthropod found in human dwellings throughout ...

The hubs of orb webs, where the spiders lurk, are usually above the center, as the spiders can move downwards faster than upwards. If there is an obvious direction in which the spider can retreat to avoid its own predators, the hub is usually offset towards that direction.
The babies can: using a tactic called “ballooning," young Joro spiders can use their webs to harness the winds and electromagnetic currents of the Earth to travel relatively long distances.
Darwin's bark spider (Caerostris darwini) is an orb-weaver spider that produces the largest known orb webs, ranging from 900 to 28,000 square centimetres (140 to 4,340 sq in), [2] [3] with bridge lines spanning up to 25 metres (82 ft). The spider was discovered in Madagascar in the Andasibe-Mantadia National Park in 2009. [4]
