What are uses of spider web and spider silk?

Answer 1

Spider's use to humans is limited, but there are many creatures on Earth whose lives are not of immediate benefit to humanity. One could also ask 'what use are humans?'!! Nevertheless, Spiders can perform three functions which benefit us. Most importantly. they catch flies which might spread disease to people. The microbes carried by flies are harmless to spiders, but can lead to illness or infection in humans. Secondly, big bird-eating spiders in South America are used as food by the native Indians of the rainforest. After spearing the spider painlessly, they remove it's round abdomen and then roast the remaining body over a campfire. A third use that some spiders have been put to, is for their webs to be spun into silk. Silk spiders live in the island of Madagascar, off the east coast of Africa- they are so named because the webs they weave are of exceptional quality, being both strong and beautifully soft. Madagascan craftspeople collect these webs from the trees and telegraph poles, and spin them into silken thread to make garments. In the days when Madagascar was a British colony, there was even an attempt to establish a large-scale spider-silk industry!!

Answer 2

Spiders use their silk to make webs or other structures, which function as nets to catch other animals, or as nests or cocoons for protection for their offspring. They can also suspend themselves using their silk.

Answer 3

There are many uses, one main reason for spider webs are for capturing prey.

As far as human uses, pound for pound, spider silk has a higher tensile strength than steel and Kevlar, and stretches to about 40% its length before breaking. About a decade ago, a Canadian inventor built a bear-proof suit using spider silk. The Dutch have made a human skik analog using genetically altered goats that produce spider silk proteins in their milk; it seems to have the added advantage of being mildly bullet proof.

It has been suggested that an artificial form of spider silk might be sufficiently strong to make possible "Beanstalks," LaGrange point space elevators that are permanently anchored to the ground with satellites in geosychronous orbits. Such stations would make travel to and from orbit much easier and revolutionize microgravity industry and tourism.

Answer 4

Spider silk and webs are used by spiders for catching prey, shelter, and as a means of transportation. Humans have also found various uses for spider silk, such as in research for developing new materials, medical applications like sutures and bandages, and even in the production of bulletproof vests and armor. Additionally, spider webs have been used in traditional medicine for treating wounds and skin conditions.
