Definition Areas dominated by slow-moving mollusks, most commonly gastropods. In general, the forms that reach densities sufficient to be defined as a Biotic Group are detritivores or suspension feeders. Slow-moving predatory mollusks (e.g., whelks, drills, octopods) tend to be less abundant, and would more typically be classified in CMECS as Co-occurring Elements, together with another Biotic Group.
