Black Mussel

紫孔雀殼菜蛤

Mytilisepta virgata

Often attach and bind together on rocky structure to form a mussel bed.

經常在岩石結構上依附著並聚集在一起形成「蛤床」

Unlike gastropods like snails which attach themselves using strong muscular feet to the shore, mussels secrete a bundle of filaments called byssus (also known as “beard” in daily usage) and attach themselves to surfaces on the shore.

與依靠強壯的腹足依附著在岸上不同的腹足類動物（例如螺）不同，蛤會分泌一束稱為足絲（byssus）的細絲支撐自身在表面上

Mussel bed create a complex structure allowing other intertidal species such as crabs to seek shelter and food.

結構複雜的「蛤床」能提供庇護所及附著表面予螃蟹或蛤貝等潮間帶物種
