Description
Definition Soft sediment areas in which starfish occur in large aggregations and clearly dominate the biota. Practitioners should note that, in most cases, starfish are predators on another Biotic Group (e.g., Clam Bed) which (as the forage base) would normally constitute the dominant percent cover or biomass. In those cases, Starfish would be described as a Co-occurring Element, e.g., "Biotic Group: Clam Bed with Co-occurring Element: Astropecten".
