Scientists have long tried to understand the mechanisms that spiders use to make their silk, and have so far been unsuccessful in attempts to recreate the silk in laboratories. What makes the silk so difficult to artificially recreate is the make-up of its complex protein molecules and repetitive...
Spiders’ multiple spinnerets and eight legs come in handy for web-building. The architecture of a web is very species-specific, says Coddington. “If you show me a web, I can tell you what spider made it,” he says, adding that spiders “are opinionated” about where they will make a...
How do spiders make silk Spider silk starts out in the silk glands as a watery gel of long protein chains, which is funnelled down a gradually tapering tube. As the tube narrows, coatings are applied to the mixture (to provide stickiness and water resistance, for example) before it emerges...
Investigating how spiders spin their silk, researchers unravel a key stepScientists from the Technische Universitaet Muenchen and the University of Bayreuth have unraveled a decisive step in nature's way of producing spider silk; with industrial partners, they are working toward biomimetic production of...

A group of scientists from Sweden have unlocked one of nature's biggest secrets. The scientists have worked out how spiders make such strong silk when they build their webs. The silk that spiders make is strong and even tougher than steel. Being able to
Their proper common names are daddy longlegs, harvestmen, or opilionids. These organisms are called harvestmen because they are often seen in large numbers in the fall around harvest time. During the fall, their populations may briefly cluster together. Unlike spiders, they do not create silk ...
Passage 2Why should most of us hate spiders when we know deeply how much good they do? Is it because they somehow seem so alien? After all, what other land creatures on earth have eight legs? What other creatures spin silk webs in which to catch and wrap their prey to preserve it for...
ID Spiders by Their WebsNow that you have a quick rundown of spider web characteristics, it’s time to gather all the data for your identification effort. To do so, note these web characteristics:Spiderweb location –Is the spider web hidden away or out in the open? Does it hang ...
