Spider. Coloured environmental scanning electron micrograph (ESEM) of the underside of a spider. At the rear of its abdomen are its spinnerets (blue,lower right),structures used to produce the silk which the spider uses to weave a web and trap its prey. Some spiders also use silk to spin cocoons for their eggs. The spider's legs and mouthparts are also seen,as well as some silk (thin blue threads). 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 | |
