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.

A spinneret is a silk-spinning organ of a spider or the larva of an insect. Some adult insects also have spinnerets, such as those borne on the forelegs of Embioptera. [1] Spinnerets are usually on the underside of a spider's opisthosoma, and are typically segmented. [2] [3] While most spiders have six spinnerets, some have two, four, or eight. [4]
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).
