Perhaps the most famous group of spiders that construct funnel-shaped webs is the Australian funnel-web spiders. There are 36 of them and some are dangerous as they produce a fast-acting and ...
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. Spider webs have existed for at least 100 million years, as witnessed in a rare find of Early Cretaceous amber ...
The web, with its shelter at the centre, is easily identifiable. The leaf curling spider cleverly weaves a leaf or other object into the centre of its web as a hide-away from birds and other predators. Leaves are twisted along their length to form a funnel, (sometimes with a silk wall on one side, if necessary) that the spider can retreat into.
The web of Darwin's bark spider is remarkable in that it is not only the longest spanning web ever observed, but is the largest orb web ever seen, at an area of up to 2.8 square metres (30 sq ft). [2] Nephila komaci, discovered in 2009, and some other Nephila species also make webs that can exceed 1 m (3 ft 3 in) across. [4]
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. [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 file snake (Acrochordus granulatus), from a family known as completely aquatic, has hygroscopic skin that serves as a water reservoir, retarding desiccation, allowing it to travel out of water. [13] Another example is the sticky capture silk found in spider webs, e.g. from the orb-weaver spider (Larinioides cornutus).
