Composition and PurposeEdit
Webbing is excreted (often liberally) from the jaws of Xenomorphs as a clear, saliva-like fluid. Much like the silk spun by spiders, it is a proteinaceous substance that hardens on drying. In its hardened state, it adopts a darker, translucent color, often varying shades of black, brown and/or green. Once hardened, webbing is relatively elastic whilst still retaining exceptional tensile strength.
It is primarily used in the construction of a Hive.
