Definition Soft-sediment areas dominated by mussel species that are not attached to a hard substrate. These animals may be resting on the sediment surface, partially embedded in the sediment, or attached to conspecifics (by using their byssal threads), or to a piece of gravel in Slightly Gravelly Fine Sediments. Individuals in the Mussel Bed Group are not present in densities sufficient to construct substrate; in that case, they would be classified as Mussel Reef.
