| Preferred label | Cushion sponges and hydroids on turbid tide-swept sheltered circalittoral rock |
| Definition | This biotope is found in variable salinity environments and tends to occur on the upper faces of circalittoral bedrock and boulders, in sheltered sites subject to moderately strong tidal streams. This biotope is characterised by aggregations of cushion sponges such as [Hymeniacidon perleve], [Halichondria panicea], [Halichondria bowerbanki] and [Cliona celata], other sponges ([Leucosolenia botryoides] and [Suberites ficus]) along with occasional hydroid tufts of [Nemertesia antennina], [Nemertesia ramosa] and [Plumularia setacea]. Other species that may be present include the colonial ascidians [Clavelina lepadiformis] and [Morchellium argus], [Dendrodoa grossularia], the anemones [Metridium senile] and [Sagartia troglodytes], the barnacle [Balanus crenatus], [Asterias rubens], [Carcinus maenas] and [Bugula plumosa]. Two variants of this biotope have been recorded: CuSpH.VS and CuSpH.As. |
