Silk

Silk, also known as web or webbing, is a natural substance produced by spiders from specialized appendages called spinnaretts located on the tail end of the abdomen.

Role in Salticid Culture
Since salticids are light and lack significant bodily strength to move heavy objects, the ability to produce silk has been the driving factor behind their material culture. It is used heavily in the creation of homes, sleeping sacs, community structures, art, and tools, along with being used for cultural necessities such as burial, hunting, trapping, fishing, and farming.

While most salticids employ a silken dragline as well as guidelines to find their way around in the dark, the production of silk in meaningful quantities, as well as the use of silk in repetitive productive labor, is usually heavily gendered in Terran societies and generally associated with secondary genders. Creation of art and the principles of aesthetic design are usually considered the domain of primary genders, who are seen as active creators as opposed to laborers, and the use of silk produced from one's own body for this purpose is accepted.

Historically, some salticid societies have engaged in a practice known as silk slavery, where prisoners of war or conquest are kept captive and forced to produce silk for the captor's society to use.
