Description

Family Mytilidae

Scars of the anterior and posterior adductor muscles decidedly unequal (the anterior scar is the smaller one, and may be scarcely noticeable); umbones generally, but not always, much nearer the anterior end than the middle , hinge plate without teeth and without a chondrophore ; usually attached to a hard substratum by a byssus of organic threads (includes some species that bore into rock or hard clay ).Mussels are members of the molluscan Class Bivalvia along with clams and scallops . Attaching to the substrate and each other with byssal threads , mussels often form dense beds that support rich epifaunal and infaunal invertebrate assemblages . Other groups commonly associating with mussels are porifera (sponges), cnidarians (including hydroids , corals , and anemones), annelids , crustaceans, bivalves , bryozoans , and echinoderms . Mussel larvae remain in the water column for several weeks. Mussels are suspension feeders , filtering plankton and other small particles from the water column. Mussels are preyed upon by sea stars, gastropods and crabs.
