  • "Sea silk sounds like the stuff of legend. Harvested from rare clams, this thread flashes gold in the sunlight, weighs almost nothing, and comes with a heavy load of misunderstanding, misinterpretation, and misinformation. But the fiber itself is no myth. Its flaxen strands come from Pinna nobilis, or the pen shell, a giant Mediterranean mollusk that measures up to a yard in length. To attach themselves to rocks or the seafloor, some clams secrete proteins that, upon contact with seawater, harden into a silky filament called byssus. The byssus of the pen shell makes sea silk, the world’s rarest thread."
