||Hard or mixed substrate areas in which starfish (sea stars) 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., Attached Mussels) which (as the forage
base) would normally constitute the dominant percent cover. In those cases, Starfish
would be described as a Co-occurring Element, e.g., "Biotic Group: Attached Mytilus
edulis with Co-occurring Element: Attached Asterias rubens". The Attached
Starfish biotic group is intended to describe areas where starfish constitute the
dominant life form in percent cover, not areas with occasional or scattered starfish.
