How Do Webs Come Out of Spiders?
WouterSpiders create a web that they use to trap their prey. Their webs are shaped in different ways, depending on their location and the type of prey. Some of these webs are sticky, while others are wooly.
A web is created using silk. Almost all spiders have a silk gland on their abdomen. These glands produce liquid silk that hardens in the air. The liquid passes through a series of ducts and cells, transforming the silk into solid threads. The spider then pulls the silk out of the gland.
The spiders spin a web, usually a sticky one, to catch their prey. These webs are positioned near dark, damp places. They are also useful environmental indicators. They help the spiders detect disturbances and vibrations in the surrounding area. These webs are constructed so that if any disturbance occurs, the spider can find its trapped prey.
Some species of spiders, such as the bolas, recycle their silk when they are not in use. The sticky silk holds the prey in place while it is being trapped.
A spider web can reach several feet between trees. They have been spinning trap webs for at least three to four million years. They are able to subdue large animals. These spiders can also be used as an alarm system.
These spiders are classified by the number of spinnerets that they have. Most have two to eight spinnerets. Each spinneret is connected to a silk gland. The silk glands are tipped with spigots.
