時間経過 BLUE MUSSEL time lapse of foot 青いムラサキ貝

Described as containing the first known protein with both collagenous and elastin-like domains, byssal threads help mussels latch onto stuff.
Byssal threads have a stiff tether at one end and something like a shock absorber on the other end protruding from the mussel foot.
Mussel can move by it's byssus thread by cutting it off and building it again. It even is able to defend itself with byssus thread by tying predator snails down with byssus threads. Mussels can spit a byssus thread 200 times longer than their shell. The threads are secreted by a special gland in the foot. The foot's tip is pressed against a hard surface and the glandular secretion passes down a groove to the tip of the foot. A byssal thread is formed when the secretion is exposed to seawater and hardens.
