Beautiful Spider Web

A spider web, spiderweb, spider's web, or cobweb
 is a device 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, southern England.Insects can
get trapped in spider webs, providing nutrition to the spider; however, not all
spiders build webs to catch prey, and some do not build webs at all. "Spider
web" is typically used to refer to a web that is apparently still in
use, whereas "cobweb" refers to abandoned (i.e. dusty) webs.
However, "cobweb" is used to describe the tangled three-dimensional
web of some spiders of the Theridiidae family. While this large family is also
known as the tangle-web spiders, cobweb spiders and comb-footed spiders, they
actually have a huge range of web architectures.
