in a web]] A spider web, '''spiderweb''', '''spider's web''' or '''cobweb''' (from the obsolete word "coppe", meaning "spider" Compact Oxford English Dictionary: cobweb ) is a device built by a Spider out of Protein aceous Spider Silk extruded from its Spinneret s. 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. The word "cobweb" is usually used for a web inside a house, where dust has gathered on the sticky silk, forming long, hanging streamers. TYPES OF SPIDER WEB There are a few types of spider web found in the wild; and many spiders are classified by the webs they weave. Different types of spider webs include, but are not limited to:
'' orb-web]] Several different types of silk may be used in web construction, including a " Sticky " capture silk, or with "fluffy" capture silk, depending on the type of spider. Webs may be in a vertical plane (most orb webs), a horizontal plane (sheet webs), or at any angle in between. Most commonly found in the sheet-web spider families, some webs will have loose, irregular tangles of silk above them. These tangled obstacle courses serve to disorient and knock down flying insects, making them more vulnerable to being trapped on the web below. They may also help to protect the spider from predators such as Birds and Wasps HOW SPIDERS MAKE WEBS Spiders have several spinneret glands located at their abdomen which produce the silken thread. Each gland produces a thread for a special purpose. Seven different gland types have currently been identified, although each species of spider will possess only a few of these types, never all seven at once. Normally a spider has three pairs of spinnerets, but there are spiders with just one pair or as many as four pairs of spinnerets, with each spinneret having its own function. |
