Physical: A common bivalve mussel, M. edulis possesses a smooth shell with pointed terminal beaks, edged with small fine teeth. The shell is glossy blue black, and the interior is a shade of violet. Average size is 2 to 4 inches in length.
Habitat: Blue Mussels range from the Arctic Circle to South Carolina in estuaries to several hundred feet offshore. Individuals form shoals by attaching themselves to any solid anchored structure.
Feeding: Blue Mussels are filter-feeders that consume plankton in the water column.
Breeding: M. edulis reproduces sexually by releasing male and female gametes into the water. Fertilized larvae are planktonic and mature to settle onto benthic structures. Mussels live 15 years or longer.
