Definition Areas distinguished by large fecal mounds or castings. These features are characteristic of larger deposit-feeding polychaetes and other mud-ingesting fauna. Mounds or castings are not always present even when these fauna are abundant, particularly when water movements (currents, waves) are sufficient to remove the deposits.
