Byssus from some species has been made into a very fine cloth.

This forms extremely tough, strong, elastic, byssus threads that secure the mussel to its substrate.

Marine mussels are usually found clumping together on wave-washed rocks, each attached to the rock by its byssus.

This is in no small part due to the evolution of the byssus, which mussels employ to tether themselves to accessible surfaces.

The researchers conducted a detailed chemical analysis of the protective outer coating of the byssus in a common species of marine mussel.

The individual byssal threads that compose the byssus are stiff, but stretchy and are fashioned by the mussel in a process resembling injection molding.

In marine mussels, the foot is smaller, tongue-like in shape, with a groove on the ventral surface which is continuous with the byssus pit.

Moreover, many other silk-like biomaterials such as elastin, collagen, byssus, resilin, and other repetitive proteins have similar features to spider silk protein.

The initial contact with the substrate is loose, if the suitable the larva will metamorphoses into the juvenile form, plantigrade, and attach byssus threads.
