Fishing for Mediterranean mussel

The Mediterranean mussel is a medium-to-large bivalve with a smooth, glossy, blue-black to purplish wedge-shaped shell, very similar to the blue mussel. Native to the Mediterranean and adjacent Atlantic, it is farmed worldwide and has become a major invader on many coasts. The shell reaches about 6 inches. It forms dense beds and stays fixed to hard surfaces. This summary was AI generated
