Spiders make spider silk for various purposes such as weaving their webs, protecting their eggs or as a safety line. The amphipod Peramphithoe femorata uses silk to make a nest out of kelp blades. Another amphipod, Crassicorophium bonellii, use silk to build shelter. Carp produce fibroin units, a component of silk, to attach their eggs to rocks ...
Spider silk structure: crystalline beta-sheets separated by amorphous linkages. Silks have a hierarchical structure. The primary structure is the amino acid sequence of its proteins (), mainly consisting of highly repetitive glycine and alanine blocks, [4] [5] which is why silks are often referred to as a block co-polymer.
More specifically, the male uses his silk to immobilize the female's legs I and II while he holds her legs III and IV. [9] Prior to mating, the male follows the female, periodically releasing his dragline (a line of spider silk). Slowly approaching the female from behind, the male traces the female's path until he reaches the female's hind legs.
The average toughness of the fibres is 350 MJ/m 3, and some are up to 520 MJ/m 3, making the silk twice as tough as any other spider silk known. [8] The web of Darwin's bark spider is remarkable in that it is not only the longest spanning web ever observed, but is the largest orb web ever seen, at an area of up to 2.8 square metres (30 sq ft).

A classic circular form spider's web Infographic illustrating the process of constructing an orb web. A spider web, spiderweb, spider's web, or cobweb (from the archaic word coppe, meaning 'spider') [1] is a structure created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey.
Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, the caterpillar of the domestic silkmoth is the most widely used and intensively studied silkworm.
Introducing Spider Webbing, a term used to describe an accumulation of toxic behaviours that have, like a web, become intricately woven together to the point where you can no longer see through them.
According to this page, the density of spider silk is 1.3 g/cm 3, and according to this page, the diameter of spider silk is 0.15 microns, and in this research they used a silk fiber with diameter of 2 microns. Let's be generous and use the 2 microns estimate.
