Description
Definition Areas distinguished by a fluid, fecal-rich, pelletized surface layer, which is typically 5 - 15 millimeters thick (Rhoads and Young 1970). This layer is characteristic of deposit-feeding polychaetes, deposit-feeding clams, and/or other fauna. This layer is indicative of deposit feeders, but is not always present in deposit feeding communities, particularly when currents are sufficient to remove the layer.
