Byssus

 

(1) An excretion of the byssal gland, found in the so-called feet of many bivalve mollusks. Immediately upon expulsion, byssus hardens and forms durable silky filaments by which mollusks fasten themselves to underwater objects. In antiquity a special cloth, vysson, was prepared from the byssus excreted by the large mollusk pinna.

(2) A roe disease of freshwater fish caused by certain fungi of the genera Saprolegnia and Achy la.

In many cases, slight differences in position between still images were found to be due to the animals repositioning, or rotating around their byssus, rather than "walking." Thus, a minimum distance of 1 mm was used as the threshold value for all translocation movements.

These metabolites may act directly on the mussel inhibiting or stimulating byssus emission.
"Many researchers have studied mussel glue before," Qin said, referring to the sticky substance that anchors byssus threads to a surface.
In fact, byssus is even stronger when facing chaotic forces; it can withstand impacts in a dynamic, sloshing environment that are up to nine times stronger than the strain of being pulled in one direction.
Whereas in the control group, normal byssus production and attachment was noticed (Table 4).
However such an environment is conducive to the entrapment of sand particles by the byssus threads of the horse mussels.
Mussels, for instance, have byssus threads that anchor them to the rock.
