- 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 mid bathyal mud and lower bathyal sand only Gracilechinus acutus norvegicus assemblages have been recorded to date. Associated taxa on sand include holothurians.
