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
This broad community contains biotopes that are dominated by urchins and occurs on sediment. The species of urchin and associated species varies with depth and substrate type. On Atlantic upper abyssal mud only Gracilechinus alexandri, Psilaster and Plinthastera assemblages have been recorded to date. Associated taxa include seastars, burrowing crustaceans and holothurians.
