  1. Sanjay Awasthi the spinneret glands located at the tip of the spider abdomen can generate different types of silk, some with very high tensile strength. According to Wiki, “Many webs span gaps between objects which the spider could not cross by crawling. This is done by first producing a fine adhesive thread to drift on a faint breeze across a gap. When it sticks to a surface at the far end, the spider feels the change in the vibration. The spider reels in and tightens the first strand, then carefully walks along it and strengthens it with a second thread. This process is repeated until the thread is strong enough to support the rest of the web.” More:
