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
All infaunal communities in the deep-sea are dominated by polychaete species with a diverse range of other taxa including bivalves, amphipods and sipunculids. Species level data were not available for analysis and at family level it was not possible to define more distinct groups for infauna.
