Biotope dominated by the barnacle Bathylasma hirsutum. Observed on bedrock in high current areas. Barnacle coverage may not be dense. This assemblage was also identified in the mid bathyal, but the associated species are likely to differ. Characterising species listed refer to all Bathylasma hirsutum assemblages not just those found associated with the zone and substrate specified in this biotope.
