Atlantic circalittoral biogenic habitat

Description (English)

Atlantic circalittoral biogenic reef communities. This complex includes bivalve reefs (e.g. mussel beds) and cold water coral reefs. These communities develop in a range of habitats from exposed open coasts to deeper offshore habitats and may be found in a variety of sediment types.
