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
Rock and other hard substrate has a more diverse epifaunal community as species attach to the hard surface that in turn attract more fauna. Deep-sea rock is generally encrusted in a range of species including sponges and cold water water corals. Rock includes bedrock mixed substrate of pebbles, cobbles and boulders, and isolated drop stones. It can occur in a mosaic with sediment habitats. Hard artificial surfaces are considered 'other hard substrate' as is carbonate and hard clay. Rock does not have an infaunal community.
