Antedon bifida and a bryozoan/hydroid turf on steep or vertical circalittoral rock
|Within Vocab||Marine Habitat Classification for Britain and Ireland Version 97.06|
|Definition||Steep and vertical slopes of bedrock in slightly tide-swept conditions with dense aggregations of Antedon bifida, in some locations with a bryozoan turf. The dense aggregations of Antedon also extend into infralittoral where they occur on kelp stipes (see EIR.LhypR). Bugula spp., Abietinaria abietina and Nemertesia antennina are often found at the same sites and there are also examples with dense Ciona intestinalis and Pomatoceros triqueter. Some examples are particularly impoverished with little beneath the feather stars other than coralline crusts (e.g. Summer Isles and Loch Broom). High densities of Antedon are widely found, sometimes also in sheltered, silty conditions. Further consideration required of this biotope.|
