Download comparative physical and biological data. The comparative tables enable a rapid comparison of the species composition and principal physical characteristics between a given set of biotopes.
- Records used to define the biotope (core records)
- Other records assigned to this biotope, marked as 'certain'
- Other records assigned to this biotope, marked as 'uncertain'
- Predicted extent of the level 3 (for sublittoral rock & deep sea) or 4 (for sublittoral sediment) habitat
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.
