Description

The shell of an adult Modiolus barbatus can be as long as 30–60 millimetres (1.2–2.4 in).[3][4] The shape is elongated and ovoid or rhomboidal with a curved or obtuse dorsal margin. The outer surface of the shell is dark brown, while the inside of the valves is blue or slightly iridescent gray. These mussles are characterized by a periostracum with long, stiff, flat bristles. They are attached with strong byssus to the underground.[4]

Distribution and Habitat

This species is present from the Mediterranean Sea to the Black Sea, on the southern and western coasts of Great Britain and Ireland and along the Atlantic coast of Morocco. It inhabits in large communities on rocks and stones the coastal marine environments at depths of 5 to 110 m.[3][4]

Human use

The bearded horse mussels are harvested for human consumption from their natural beds, together with Mytilus galloprovincialis.[3]
