Caption

Spider spinneret. Coloured scanning electron micrograph (SEM) of the end of a spider's abdomen showing silk (threads) being produced by a spinneret. Spinnerets produce the silk which spiders use for a wide variety of purposes, such as constructing webs and shelters. 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. Magnification: x600 when printed 10cm wide.
