Description
A biogenic structure is formed when reef-forming species, such as cold water corals, attach to any hard substrate present and grow over the surrounding area forming a secondary substrate over the top. This changes the composition of the associated community as it provides a stable surface for epifauna to attach. Biogenic structure includes only areas where the seafloor is completely covered, not isolated structures, such as sponge aggregations or discrete corals.
