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
Circalittoral rock features include circalittoral fouling communities (CR.FCR.FouFa) and circalittoral caves and overhangs (CR.FCR.Cv). These features are present throughout the circalittoral zone in a variety of wave exposures and tidal streams.
