Description
This broad community contains assemblages where sponges dominate sediment habitats. Sponges can be of all morphotypes except encrusting. Aggregations of the Geodia species with other massive forms are typical of Atlanto-Arctic upper bathyal coarse or mixed sediment. Associated species are likely to differ on different sediment types.
