Spider's spinnerets. Coloured environmental scanning electron micrograph (ESEM) of the spinnerets (blue) on the rear of the abdomen of a spider. These structures produce the silk (thin blue threads) which the spider uses to weave a web and trap its prey. Some spiders also use silk to spin cocoons for their eggs. Spider's silk is made of a protein polymer called fibroin. It is very elastic and can be stretched 30-40 percent of its length before it breaks | |
